We had a great stay at Toshi's place. The host was always quick to respond to any inquiries we have and the space was perfectly spacious for my family of 3. The loft (upstairs area) is actually much more spacious than what is shown in the picture.
The location of the apartment was very convenient as there is a supermarket a 2 minute walk away and it is close to the station. The available stations also sit on major lines so it made traveling to most of the major stations (such as Tokyo, Shinjuku, etc.) as well as the greater Tokyo area (like Yokohama) very easy.
