My family of 4 (kids aged 12 and 7) stayed at Alexis & Clementine's flat for 4 nights. It's a lovely, quiet flat in a very central location in London. The Heathrow Express was a 20 minute train ride to Paddington Station, and the flat is a 5 min walk from there. The flat has a day bed that pulls out to a double bed, which is where our kids slept. The listing says the bedroom has a king bed, but Americans would call this bed a queen. It was very helpful to have a washer/dryer machine. The bathroom sink was clogged when we arrived, but we made do with the kitchen sink. It would have been nice to have a little more space to unpack, perhaps one more shelf or drawer. These were minor issues, though. Alexis was very communicative and responsive as a host. Overall, we were pleased with our stay and would recommend the flat as a particularly good value for a family visiting London.
