Attended a Palestine Gaza black tie event at this prestigious venue. Located main road Central London with branded high street shopping streets. Parking is available on streets and carparks nearby. Hotel is beautiful and staff are friendly. Large hall was booked and setup was amazing. The food was from catering company and everything handled by venue was brilliant.

Great staff and service. Nice amenities. They really took good care of me. I had a treat every night I stayed there: from fresh bottled orange juice to cookies to a box of chocolate. Great location in the Mayfair area. Quiet room and a very comfortable bed. Only reason i have it a 4 was some minor stuff like no convenient power outlets near the bed or in the bathroom. Made it hard to blow dry my hair.
