Hundred Stay, Shinjuku, Tokyo.

This is a serviced apartment and hotel, located close to Shin – Okubo station on the JR Yamanote line about 15 mins. walk from the huge Shinjuku Station. We stayed there for a week in Jan. 2012
The Hotel seems to be an older building that has been renovated to suit its present purpose. The layout of our 2BR apartment was a little quirky, but not in a bad way. The apartment consisted of lounge/ main bedroom separated by sliding doors, small kitchen, and second single bedroom off to the side, with a step down you have to watch. This room has no windows. In both rooms there was plenty of storage space for our clothes. There was a special cupboard which I finally worked out, was for putting your shoes and and changing into house footwear.

The hotel is relatively easy to find about 400m from the station. Check-in was smooth and fast, front desk staff had enough English for most things. They were also very helpful, particularly with the set-up of my new ipod which this old fool couldn't do by himself. Above and beyond, as it took some time.

Fixtures and fittings were not luxurious but good enough for the price. Stove, microwave, washing machine, proper fridge/freezer, excellent storage, two bathrooms – one very small, but appreciated. There were two TV's, and a Bose stereo/dvd, and a radio with ipod dock. Light cotton robes were provided. There were also knives, forks etc. Lots of kitchen cupboards. Free internet (cable provided) and wifi in the lobby (password needed). The rooms are serviced daily or less depending on your rate/stay. The view from the 14th floor is basically of central Tokyo, nice at night. Traffic noise is minimal, windows have been retrospectively double glazed.

There is a small gym, and a business centre with computer/ internet provided. Breakfast is available in a cafeteria space for Y600, no more than adequate (for a teenager ) but there must be 50 or more dining options within 100m, including a Tesco attached to the hotel.
This is not the centre of Shinjuku, but it's an easy walk, 12 min at a reasonably fast clip, and the station – Shin Okubo, is just an uncomplicated suburban station where you can't get lost. So you can work out the system without huge pressure. An advantage IMO. Getting to many tourist places is relatively simple therefore.
Check out very quick, one of the desk staff disappeared outside to get a taxi and we were on our way home. 
There was just one minor problem. Instructions for some of the equipment could be better: the electric jug was a bit difficult to use at first, for instance. But on the whole we really enjoyed our stay and would cheerfully come back.

I stayed with my wife for my business trip to Tokyo. A few minutes walk from both Okubo and ShinOkubo JR line station, being located in the Asia ethnic town with lots of place to dine and drink, right next to Shinjuku and a few station away from Harajuku, Shibuya area, I would highly recommend here for leisure purpose stay especially for couples and families. From Haneda or Narita airport you can take the limousine bus to Shinjuku station and either hopbon the train for one station or get a taxi for small fee (710-800JPY). The rooms are spacious compared with the normal hotels in the same price range. the receptionist speaks good English, which is still a rare service in most mid range hotels in Japan. The rack rate on their site is not so easy for viewer to understand, even on Japanese language, but you should be able to find reasonable rate on booking sites, such as Agoda, hotel.com etc.

The men working here are very polite as indeed are most of the staff. It is not their fault that this is an overpriced hotel. By the way their English is very good. The online site gives the impression it is an apartment hotel, but be careful when you choose a room on the net since it may be just a hotel room rather than the apartment you think you are choosing. For $200 per night at time of writing we really got an overpriced hotel room. The carpets are tired and the whole place needs a good going-over if they are going to keep charging this amount. The view of Tokyo is pretty good but hardly worth paying $200 per night for. It is attached to a convention centre and when you wind up by accident in lifts with businessmen, they may tell you that the layout of the building confuses them too. Just finding the entrance the first time was difficult as you have to lug your luggage around the building to the door. Returning to your room can be confusing as the signage is not all that clear. If you do your washing (it is free) it is a real maze just finding the laundry; we got lost repeatedly just trying to find the laundry again. And we did have to go back and forward many times because it took forever to dry the clothes in their listless driers (Washing machines with a dry switch). Put your clothes in there for 5 hours. But who wants to spend their precious time in Tokyo going back and forwards to the difficult-to-find laundry? We finally just put our clothes in for 5 hours and went all the way to Ginza for an outing. After getting back about three hours later our clothes were still damp. The apartment you think you are getting would cost heaps more than $200 if you decided to upgrade. Coming from Okubo Station look out for the tallest building. That is Hundred Stay. Their instructions on their site are not that clear. It seemed like some of the hotels in Bali and Vietnam that are used to foreigners just accepting rather poor conditions. I should have known by looking at Tripadvisor reviews, because the Japanese reviewers gave this place a hammering whilst the foreigners thought it was great- most of them are probably not that accustomed to Japan and expect Japan to be expensive etc. But this was one of many hotels we used all over Kyushu and Honshu and it was in comparison poor value. It was the most I have ever spent on a hotel room and I expected to be great. But I was disappointed to see that it was not only the most expensive we used but the worst. No reflection on the staff- the cleaners and receptionists do a good job. But it really is overpriced.

My partner and I decided last minute that we wanted to stay in Tokyo over New Years as opposed to having to take the train home very early in the morning on the 1st. As a Westerner in Japan who tends to want to stay at Western chains, in can be difficult to find a reasonably-priced hotel in Tokyo, especially the day before, or the day of, your stay. And this was the beginning of New Years weekend, so I was getting myself prepared for an even more arduous search. Hundred Stay, however, made the search quick and incredibly painless, and I couldn't have been happier with what we received.

The hotel is a very short walk from Okubo Station on the JR Sobu-Chuo line. This is pretty convenient if you know your way around Tokyo/Japan on the JR lines or on the Tokyo Metro. If you don't, however, you may find the need to change trains a little cumbersome as Okubo Station is only served by that one line. Regardless, Hundred Stay is just a stop away from Shinjuku, and only a few minutes by train or taxi from Shibuya, Harajuku, and the rest of the great Tokyo areas. So location is definitely a plus for this place.

The rooms are relatively spacious by Japanese standards, which is to say that they're almost on-par with what I'd expect at a Western-owned chain hotel. We stayed in the most basic room, too, so I was even more surprised. It had a flat screen TV, a Bose sound system and DVD player, an iHome for iPods and iPhones, and free wired Internet (no WiFi, though) which was great. All this was set upon the small-ish desk in the room, though, so that made the flat surfaces in the room, minimal as anything else like wallets, phones, jewelry, watches, suitcases etc had to be set on the night stands or on the floor. My partner and I don't have much "stuff", though, so this wasn't really a big deal. Plus, there were several closets for storing/hanging clothes, which came in very handy.

The bedding was ample and we were definitely kept warm throughout the night, even if we hadn't had the heater running. The mattress was on a bit on the firm side, as other reviewers have mentioned. I would have also like to have had a couple more pillows in the room, too, since hotel pillows tend towards the thinner side. To be honest, though, I had no trouble falling or staying asleep. So I guess the bed wasn't really that big of an issue.

The bathroom was very large by Japanese standards and had a normal (for North Americans) sink/counter, toilet, tub arrangement as opposed to the moulded plastic bathroom insert-like set-up common in most Japanese hotels. That is, the tub was a real tub, the toilet was a separate entity not attached to the counter/sink unit. I know this sounds odd, but it's nice to not feel like I'm bathing in a tiny train/airplane bathroom. The water pressure in the shower was amazing, the water very hot, and I love that they stocked Pola AromaEss bath products - a personal favorite of mine and only available in hotels or online. It's one of those little things that define a certain quality of hotel for me...like fitted sheets instead of flat sheets on the mattress.

A friend of our was staying at the same hotel for roughly the same timeframe and happened to get lucky due to overbooking and was upgraded to a studio/suite. The room was huge! It was wonderfully appointed with couch and living area, as well as a small dining table/chairs, a small galley-style kitchen, washer/dryer, and a giant walk-in closet. And he only paid about ¥2,000 more than we did. And he had a great view of downtown Tokyo. I was kind of jealous, actually.

The front desk staff are gracious and helpful, but not all of them speak English. Fortunately I am pretty well understood and can get by so long as the conversation stays simple. However, I think tourists with no working knowledge of Japanese could have trouble if one of the less linguistically-inclined staff is working the front desk. However, I've always found that lots of pantomiming seems to help, too. So, if you don't speak Japanese, work on your charades skills.

The only real complaint I have is that there's a lot of security, which is generally a good thing though a bit unnecessary in Japan. However, this manifests itself with multiple keyed entries throughout the hotel. So, after 10pm you have to use your key to get into the lobby. Then once in the lobby you have to use your key to get to the elevators, then your key is necessary to get to your specific floor, then finally into your room. This is a small annoyance, but it's compounded a bit by the fact that the key cards have a very similar front and back, and the key card must be inserted a certain way. It's all just kind of an "ugh...c'mon!" moment, but if you just want to get back to your room (or you have to use the bathroom badly), it can be cumbersome.

Overall, this hotel was an excellent choice I just happened to stumble on via Agoda.com. Because I loathe that the trains stop at midnight, this hotel is going to be my go-to lodging in Tokyo if I plan on staying the weekend. I honestly can't rave about it enough. It's convenient, affordable, and an excellent stay all-around. Highly recommended, and have already recommended it to friends coming to Japan for a visit.
