For Australians and Americans used to an average sized house this place may well be much smaller than it appears, space being an extreme premium anywhere in Tokyo, however it was nice and cosy once we got some sleep in. Walls and sliding doors have very effective sound proofing even though they are thin. Street shops, convenience stores and the local rail are all within 150m walking distance. You may end up with 2 or 3 small flights of stairs depending on what room you get from the lucky draw.
