We had a great time staying here. The house is tucked away in a peaceful area (very important for tokyo) but still a short walk to the busy shinjuku area. It is also in a great spot for the yamanote line.
The house itself is very clean, with great facilities and a comfortable size for a family of 4. I would definitely stay here again if I return to Tokyo.
Host was great to deal with, always providing quick and helpful responses.
