I'll absolutely recommend Keiko's house to other travelers. She is a very kind and thoughtful host. She prepared everything we needed in the house and guided us to her house. When we had problems she came to help us very quickly. The house is specious for our big family with 5 adults and 1 kid. It's very clean and modern with Japanese style. We also enjoyed the nice and comfortable living room, it was good for us to hang out after a day's trip. The location is very good indeed and this is a big plus for Tokyo first time comers like us.
