A fantastic stay in every way. The staff were highly attentive and helpful, the rooms were comfortable and quiet, everything is kept immaculately clean, and the dining and afternoon tea were wonderful (and I loved the American Bar - world-class cocktails!). The location is just fantastic - short walks to Green Park and the tube (through the Queen's passage, a tunnel just outside the front door of the hotel that takes you into the park), Buckingham Palace, Westminster, and Piccadilly Circus. This is my go-to London hotel.
