Masato-san have a very quick response. His house are only 5 mins walk from station and near the station there's a quite big grocery. His house also have a modern equipment, very clean and spacious, more than enough for 9 ppl. It was a pleasurable stay and I would prefer to stay there again. The main cons only its location are 20-30 mins train ride to shinjuku. Aside from that, it's a perfect experience.
