We had a wonderful stay at Yasuko's guest home! My husband, my parents and I stayed for three nights and the accommodation worked perfectly for us -- we were all able to stay in one place while still having enough room for everyone. The tatami rooms are beautiful, with beautiful ceramics decorating the house, and very comfortable futons to sleep on. The neighborhood of Koganei has a great mellow feel, which is a nice contrast to downtown Tokyo, while still being easily accessible to downtown Tokyo. We also very much enjoyed visiting the Edo-Tokyo Open Air Architectural Museum in Koganei Park.
