This flat is in a quiet, posh location, about a 10-minute walk to a grocery store and to either of two Underground stations. The bedrooms are small but perfectly comfortable, with one opening onto the outside garden. The other has a built in bed that our kids liked, and also a desk. Kitchen and laundry facilities were satisfactory, although it was difficult to figure out how the washer/dryer unit worked (we downloaded a manual online for some guidance). Due to travel delays we were a bit late for the initial meeting with the flat's caretaker, but she was patient and friendly, and we had no difficulty getting in and settled. We didn't meet Ollie, but he was on top of things via email and text, and was responsive to our needs. We had a great stay there and would not hesitate to work with Ollie again.
