I rented this flat for my family for our summer visit to London. It was very bright and extremely spacious, with plenty of free space for the tons of shopping bags we had during our stay. We chose it mainly for its location, because it is right in the middle of Mayfair, very close to many restaurants and bars, and with really good transport connection to any place we wanted to visit in London. I think we definitely made the right decision of not choosing a hotel: we had much more privacy and comfort, and for those few days we stayed there we felt like home, as if we were some locals there (if you don't take into consideration the I Love London hoodies and big cameras around our necks). There's a washer and dryer on the same floor in case you need to do some laundry (we found this quite handy and travelled with carry-on luggage only). Highly recommend it!
