Incredibly great and helpful host. The flat is at a great location (bus to Piccadilly stops just at the corner, there in 15-20 mins), but you have to walk like 7 mins or so to the nearest tube station/greater stores and even more for playgrounds, which might be a problem with small kids (when travel times double). Also, note that the place is very compact, but miraculously well organized, so we (2 parents + 2 toddlers) had no problem with its size.
