Chieko was very responsive and gave clear instructions on how to find the house, how to get in, as well as provided very useful information to surrounding areas and how to operate various things in the house if you can’t read Japanese. I stayed here with a 4 year old, a baby, my mom, my brother, my two sisters and her two teenage boys. We were very comfortable and felt right at home. They arranged the beds accordingly to the people staying there and even provided a crib and high chair so that was convenient. The house is about 10 min walk from the station so I suggest arranging for taxi or car pick up to and from the airport, but otherwise, once you get to the station, it is convenient to get to Shibuya, which is nice. The house was very clean and had many of the basic necessities. I would recommend this place for any bigger groups or extended families traveling to Tokyo.
