Private locking room with extremely hospitable, thoughtful host. Bikes and breakfast provided. Wonderful park nearby, nice bike ride to various nearby universities and the NAOJ. Lots to explore. Very nice way to immerse yourself gently in Japanese culture and get lots of Tokyo city tips. The house is in a very location, but it's a little bit of a walk to the train station, and no convenient bus route--I recommend using JapanTaxi to get to and from the station when you have luggage. There is one flight of stairs to the bedroom.
