We spent a great time in japan among others thanks to koshio and his hospitality. The neighborhood is quiet and its only a 10 min walk to mitaka station. We booked the room for 4 people and there was enough space. Its a nice accomodation with japanese atmosphere since the rooms have a typical vintage japanese look. Koshio is reliable, friendly and always replied fast to messages.
Thank you very much!
Best wishes from germany!
