Great location, next to Hiro-o station, a vibrant expat area, in a surprisingly quiet street despite being a really vibrant area and very safe. Very easy to get around via subway, bus or taxi. Mick (the host) was welcoming and friendly, picked us up at Tokyo station and drove us to the house. No problems with the house itself -- spread over three levels, stairs are quite steep but there is a nice little outdoor deck on the roof. Provision of a mobile wi-fi device was a really nice touch, meant we could navigate with Google Maps on our phones while out and about.
