Wonderful Mayfair location in a private quiet side-street, with numerous restaurants, shops, and stores within a few blocks. Rooms were of a good size, both bedrooms and common area, and bedsheets and towels were of an excellent quality. Apartment was cleaned & serviced each weekday and cleaning staff were very courteous and accommodating. One helpful addition would be to have a few more coat-hooks in the hallway since London in January is typically rainy.
