This is a very unique house! To access the bedroom requires two climbs up a ladder and some shelves, if you are scared of heights or have any difficulties climbing then this house would not be suitable. The house is well stocked with everything you need and Shin was a great host and provided us with everything including directions, recommendations and toothbrushes!
It is well located very close to Hatagaya station and shops, restaurants etc and with easy access to Shinjuku but is a little quieter than Central Tokyo. The house is narrow so everything is quite small but everything 'slots' well together. We had a great time!
