The stay was really nice, and the appartment well equipped : full kitchen, laundry machine, kotatsu ; the room with tatamis and futons was really confortable. The neighboorhood is also calm and lovely, though a bit far from some touristic part of Tokyo (but really well connected through the Oji station).
The hosts were kind and providing, very attentive. We'd love to stay again in this place and totally recommend it.
