Ryota's place is spotlessly clean, and has a really nice feeling. There were six of us staying and we felt there was plenty of room. The location is very good, only two blocks from the shinjuku national gardens and local metro station. Or if you prefer walking, nice interesting walk to downtown bustling Shinjuku. The street is quiet. And the windows excellently insulated,which made for comfortable sleeping, as did the beds. Only minor thing is the single bathroom, but not a major issue. Overall. I would highly recommend this place as a great place to stay to explore wonderful Tokyo!
