We had a wonderful time in Thao's house. He is very good at communicating and he was there when we arrived to show us his place around. Although, the room itself is much more small than it appears, just like everything else in Tokyo, but keep that in mind if you're bringing lots of luggage. We had 2 futons to sleep on (very thin) individual size and there was no more space to keep our luggage visible. The bathroom is super high tech and very interesting to use. The house is exactly 1 minute walk from a train station and a supermarket, which is super convenient. But if you are using the JR pass (as we did), that station might not be convenient for you since it is not part of the JR line. In general a very good experience!
