Andy is a great host. I came very late when checking-in, and he contacted me back even though it was after 1 AM to instruct how to get into the house.
Overall house is quite clean. the room is big. the distant from the house to the tube (to me) is like 10 mins walk to Wanstead station. but not bad. but if you carry large luggage, it could be a bit distant. and the house is located in Zone 4. FYI.
We could drop by at the Leytonstone tube station, then take a bus (145 or W13) then this will shorten some walking as the bus will stop very near the street where the house located.
