The amenities of a five-star Jumeirah Hotel, combined with decorum of a Mayfair manor, are the attributes that distinguish the Grosvenor House Apartments. The new hotel residences are palatial, as each of the 133 apartments contains more than 4,800 square feet of living space. Premium services for guests will include a 24-hour concierge, daily maid service, a gym, 24-hour in-residence dining, and in-home service from the Spa Illuminata. Many of the luxury residences overlook Hyde Park or Mayfair. Others open onto a new seven-story atrium with a vaulted ceiling. Short and long-term options are available. Reservations for the Grosvenor House Apartments are now being accepted. The grand opening will occur on April 2, 2012.
