For a room in Tokyo, this price is hard to beat. It's a short walk away from Fujimidai station and is in a quiet neighborhood. When faced with the bustling environment of high volume areas like Shinjuku/Shibuya, it was super nice to come back to a quiet area to cool down. The room had all the basic necessities and for a solo traveler like me, worked perfectly. I think 1-2 would be a good match but trying to fit anymore would probably be a stretch. Taturo is a very nice man and responds quickly to any questions/concerns you might have. Also, there's a super handy guide book he provides within the room.
I would absolutely stay in his place again, if I ever came back to Tokyo.
