The location is great, not in the animated center of Tokyo (20 minutes by train from Shinjuku) but near a lot of accomodations (convenient stores, supermarket, organic stores, cycling path to Kichijoji, park, restaurants, 2 trains stations : Yasaka and Kumegawa).
Sohei and his assistant Rajikomal are very reactive, very nice people.
Unfortunately, the place was cold and not the cleanest. But Sohei provided us with another heater as soon as we told him it was cold.
Thank you!
