Excellent stay in David's flat. 10min walk from tube station that is on the Picadilly line that connects to LHR. Less than 5min from the Coop - a full grocery store. Bus stop across the street. The beautiful park right outside is great bonus for morning/evening walks/runs. The clock tower in the park is of historical interest. Good sprinkling of places to eat within 10-15min walk.
The flat is great. We used the pull-out sofa as a second bed in addition to lower bunk bed and the main bedroom. The clothes drying rack worked out just fine and goes well with compact washer. The washer is loud but we learnt to use it during the day and it was not a problem. A clothes rack would be nice addition. Nice little backyard would be perfect in the warmer season.
The kitchen is self-sufficient. You may want to bring your own pour-over coffee apparatus to go with David's kettle.
David was very responsive and helpful with arrangements for delivering our bag that had been misplaced by the airline
