 Unfortunately once we checked in and went to our room we found that our key was faulty Other guests had complained of this while we were in the lobby Altogether it took only 30 40 minutes to resolve but it doesn t make a good first impression London is hot during the summer so the room was humid and stuffy We put the air con on and opened the window only to discover the windows either aren t designed to be opened or quite old and falling apart The latch wouldn t keep the window up and it was too heavy to close ourselves It s disappointing that such a lovely hotel haven t updated their windows 
 The location of the hotel is fantastic just one tube stop away from Victoria Station aim for Green Park Check in and check out was quick staff were very friendly and helpful the decor of the lobby and bar is stylish The room itself was comfortable with plenty of space a good bathroom with shower and bath tub The room is completely spotless and housekeeping staff are very polite The main selling point of the hotel is the fantastic location Mayfair is discreet and quiet you can easily walk around and relax perfect for a weekend away with someone close If you acknowledge the bad parts as just one of those things and instead focus on the beautiful surroundings then you ll be very happy with the hotel
