We stayed for ore than three weeks over Xmas and new year and the hotel more than met expectations. It's London and Mayfair so not cheap but so are many of its competitors who do not always measure up. Staff were superb and did everything possible to cater to our needs. Upgrade and get access to the excellent executive lounge it offsets a lot of London costs. The room was excellent and they supplied an extra fridge free on request (need it for cokes since Marriott is a Pepsi haven - yuk). All other services are top class.
