This is a great place. The host speaks excellent English and takes a great pride in his house. If you want a quiet place with a real sense of a traditional Japanese house this is perfect. Easy to get to from Haneda or Shinagawa. There is even a beach nearby where you can watch the planes coming into the airport.
The room was spotlessly clean and the futon very comfortable. I slept very well.
Thank you Mr. Kato. The man with the ultimate man cave.
