We loved the Dormy Inn! It was our first experience with this chain.

Admittedly the rooms were a little dingy. But they were clean and for us the other amenities outweighed this aspect.

The location is fantastic. It's on the Sumida-gawa (Sumida river) directly across from Tokyo sky tree and Asahi beer hall. There's a walking path along the river and yakatabune rentals right below the hotel. You're also just blocks away from Senso-ji and Asakusa jinja, some of the most visited sites in Japan; and the kitchen ware streets (Kappabashi-dori). Asakusa is just a great district to wander around.

Get a river view room if you can. The window and door opened on to a small balcony. Our rooms had a mini-fridge; teapot and matcha; yukata & slippers for use in the hotel, and people totally wear these around.
It's best to get more than one room if you have more than two people.

There were so many services in this hotel we appreciated
- nightly free noodles (ramen in shoyu sauce). They were delicious! I gather this is offered at all hotels in the chain.
-onsen. No tattoos allowed but they'll give you patches to cover them. The baths have separate hours for men and women. They're on the top floor of the hotel and there's an indoor hot tub, cold tub, and sauna, plus an outdoor hot tub and benches to sit on and take in the view - watch you don't create your own view in return! ;-)
-foot bath - also on the top floor, this is outdoors and fun to sit and take in the view
-laundry machines available (washer and detergent were complimentary, dryer available for a cost)

This hotel used to be good but it has gone down hill. The Japanese breakfast is extra and used to have fish, but now does not. Very expensive extra for what it is. The rooms are dirty and carpets stained. The rooms are super small and even with the air conditioning on, the air in the rooms is stuffy and smells a bit "off." They are militaristic in the check in and check out times. At exactly 11 am they called me to ask if I was leaving despite knowing I needed to help my elderly father. On that note, he was extremely ill and they charged us ten dollars extra for him to stay in his room for a mere hour extra until we could reschedule his flight home and book another hotel as they were full. They were incredibly rude about it. He is 95 and their attitude was really unsympathetic. I will never stay there again. The Meguro property is better. Oh, and the hot spring bath they advertise is only available to women at the most inconvenient times. Sexist, too. My room rate also did not come with cleaning. Can you imagine charging EXTRA to clean?

We stayed at the Dormy Inn for 4 nights (24 April - 28 April ) and what a great stay. Fantastic location, accessed directly from Narita and right in the middle of Asakusa. Rooms not huge but reasonable size for Japan and as usual with hotels here, spotlessly clean. Great breakfast and really helpful staff. Would stay here again and would recommend. Free hot foot spa with great views and free onsen, although we did not use this and free washing machines.
