The Mayfair hotel is centrally located, close to St James, Green Park, Piccadilly,Buckingham palace. The hotel has rooms/ floors that have refurbished their rooms and these are nice, clean and comfortable. However there are rooms that are seriously outdated with old, lumpy mattresses, old carpet, stained tile in the bathroom. We were placed in such a room our first night. The following day I spoke with customer service Azhar, who was very accommodating and found me an updated, comfortable room after consulting her supervisor Max. We were moved without trouble and our remaining nights were fine. So keep this in mind if staying at this hotel. It is very old and you may need to ask to be moved.
