My husband and I stayed here during Christmas. The hotel itself is situated in a very handy location with the trains just below and a 5 mins walk away. There were also shopping centers filled with restaurants and a convenience store all near the hotel, again 5 or so mins walk away. We managed to see a lot of Tokyo so it was very handy to have the trains so close to the hotel.
The room itself was ok sized, we opted for the moderate room. Definitely a great choice as the other rooms are a tad smaller then the one we had, it was spacious enough to hold two large suitcases. The bed was comfy and large enough for 2 people. The bathroom was ok, although needed revamping but was still clean. The toilet was separate to the bathroom, had to move from the bathroom to the toilet but didn't mind. The toilet was clean and Japanese design.
The staff at the hotel were uber friendly. We only had one grumpy staff member upon checking in but for the rest of the time there everyone else was so friendly and helpful, when we needed help with directions or general questions.
The only thing we struggled with the hotel is room service. At times when we've had a long day exploring and walking we just wanted the treat and luxury of room service. Although we had restaurants nearby, many, sometimes when it was cold we just wanted to stay in our rooms in the evening.
Haneda airport is only 30mins train ride away, and only one line from the hotel, we used this both ways when using the hotel. It was very convenient and cost effective as the taxis are expensive and shuttles take a long time as they need to stop at different hotels.
As most reviews have said, this hotel is a great location and very convenient with plentiful of restaurants nearby.
