Decent location, roughly 30 minute underground ride from Heathrow and 40 minutes from most places in the center I went to. Clean. Not going to nitpick on which things not worked. My only real issue was near-constant smoking downstairs. This place is half a flight of stairs up from the ground floor. Both windows open into a small backyard which is not easily ventilated. Hosts tell you to keep windows open otherwise moisture from the shower will not dissipate. But folks use the yard as a smoking area morning, day and night. This place has no ventilation other than the windows. So you will breathe smoke. Suboptimal, especially for a "non-smoking" place.
