100% recommendation! Norimasa is a great host. He was always very kind and helpful for all our needs and information e.g. places to eat. The location is quite nice, just a few minutes walk from Nakano station from where you can ride to anywhere in Tokyo within a short time by the train or metro. There are many convenience stores (24/7 open) or restaurants in the neighbourhood. As the room is tatami and beds are futon, you can put futons aside and can utilize the room space sitting on the floor. I would come back to Norimasa at any time when I am in Tokyo again.
