Host was friendly and met me quite late near the bus stop which is probably less than 100 m from his flat. Flat up 2 flights of stairs. Accommodation is spare bedroom that was a bit messy, and hairs on the untidy sheets made it feel as if someone had already slept there and was not properly cleaned. Had to ask for a towel, but was happily provided. Given very expensive alternatives for someone who needs to wait for a flight at Heathrow, it’s quite close to the terminal (15 pounds for Uber to Terminal 3). If you’re desperate for a little sleep before traveling, the host is nice and it’s ok.
