Very enjoying staying at this house.
Katsu-San as a host is very kind, trying to help us as good as he can during our stay at tokyo, fast response, he even let us check in earlier when we arrived at tokyo.
His house is very clean, the room is big. The bathroom also big enough. The equipments and amneties are so complete as your staying at home not apartment.
Altough it seems a bit far from station, but the you wont feel that because you will pass sensoji temple as you walk to the house.
Overall my staying here felt like at my own home.
