Shin was a great host, he provided very detailed instructions to get to his house from the station which were easy to follow. He communicated very well with us prior to staying there and during our stay. He also went to great lengths to help us with some tickets we had lost - he liased with the museum and managed to work something out so that we could still visit the museum which we are very grateful for! The house is definitely a unique one! As previous reviews have mentioned, it is not recommended to stay here if you have children as the stairs are quite precarious. Once you get used to the stairs then it is not so bad. There were many ammenities at Shin's house that we could use, including a washing machine which wsa very convenient. Just a note that we stayed in winter, and the heating did not extend to the lowest floors so it could get very cold (toilet was on that floor it could be a little bit uncomfortable). The other floors were well heated though. The location is also great, only a short walk from the nearest train station and you could also walk to Shinjuku in 30-40mins if you wanted!
