Very good service, clean, modern and nice rooms, close to the JR station and all that at an absolutely fair rate. This all makes the Kameido Flex Stay a place to remember and to return, if you are in Tokyo for short visit or a business trip and do not need all the fancy an glittery things around one of these luxus hotels. The only negative thing to mention is that the wall are quite thin, so you may watch the same TV channel in silent mode than your neighbour ;)
Still I liked the stay and will come back.

We stayed here 7 nights during our trip. The staff was courteous and very good at English. The rooms were dorm like, but clean, quiet and comfortable.

We found a lovely place right on the boulevard between the hotel and train stop called the Side Room Cafe and Bar. Kyoto, the female owner, speaks English and is WONDERFUL to tourists! We stopped in every night we could on our way to the hotel and became friends with her!

This was our first trip to Japan so we weren't sure what to expect. The staff spoke English and was very accomodating. The rooms were clean and the beds were very comfortable though the room was smaller than what I was used to having in the US. I was impressed with how quiet it was. We really enjoyed the area with so many shops and restaurants nearby. It was also a short walk from the train station. I would definitely stay at Flexstay Inn if I ever have the opportunity to visit Tokyo again.
