We had a nice stay at Jay's apartment- the communication was smooth from before the arrival to after checkout; he's accommodating of special requests (like leaving the luggages in the common area after check-out). There is a dryer/washer in the apartment which is a real plus! The apartment is around 20 minutes walk away from the closest underground station but is easily reachable by bus which comes every 5 mins or so. Heathrow Airport is also a few stops (~30mins) away on the same underground line which is also convenient.
