Flat is impeccably clean, and location is absolutely perfect, not just tube but good bus lines ( direct from Heathrow, to city centar). Veronica is excellent host. Flat is big, enough for four of us ( three teenagers), bathroom is big and has big window , which can be opened fully. In back garden there are some squirrels. Picking up and leaving keys is so comfortable (from 09:00-21:00). Kitchen has everything and more than you can need. Bed and sofa bed are comfortable and linen is clean, towels also. We really enjoy our trip to London and hope to come again.
