This place was great and I couldn't recommend it more highly, especially if you are traveling alone. Ryuta is a very friendly man who greeted us at the door and showed us around his house. His house is full of all the cookware, coffee, tea, bathrooms, showers, washing machine...etc that you could ever need.
There are 5 different rooms with each one hosting 1-2 ppl in it. Not having been in a hostel type place in over 13 years I didn't remember what to expect, but the stay was great! Met a lot of people from around the world and we gave each other recommendations on what to see around Tokyo!
