My friend and I stayed here during our vacation in Tokyo. The place was great for its price and we had no issues with it.
The staff at the front desk mostly spoke English, so check-in/check-out and other inquiries were easily handled. The whole place is clean as you're supposed to take off your shoes and place them in a shoe locker at the entrance, which ensures the whole hotel stays shiny.
The room was decent in size, with the bathroom being the only letdown. There was no place to change in there, but otherwise it was fine. It was a small bathroom with just enough room to do your business and shower/take a bath. For the price point, it was a nice luxury to have your own personal bathroom.
The sleeping itself was also pleasant. The room is a tatami room, so you sleep on a futon on the floor. Zero issues, it was comfortable and easy to put away.
The room also had some great luxuries. Personal kitchen for simple cooking, an aircon, a fridge, a kitchen sink, a microwave, hair dryer, etc. The extras more than made enough for any other shortcomings about the room and made the stay very pleasant.
Overall, this was a great hotel and if I'm ever in need of staying in downtown Tokyo again, I would choose this place.
