Great house. It was perfect for our family of four (2 adults/2 kids). There was an additional room upstairs that we never even used. It was cold while we were there but the house had great heaters. The location is excellent - just a short stroll from Otsuka station on the Yamanote line. Good supermarket nearby and a nice selection of restaurants. We'd definitely recommend this house and will return there the next time we're in Tokyo.
