The house is not so large but really nice and convenient for one or two people to live in. It is not in the center of Tokyo, but we can go there by Kensei Line easily.
By the way, Hiro and Yasuko are very very nice. It is very happy to chat with them and of course they are willing to help you if you have any trouble.
If you want to have a deep communication with local people, do not miss Hiro and Yasuko' house.
