Marble Arch is near Hyde Park, Oxford Circus, and Mayfair. So great restaurants, great shopping, and wonderful walks. But also many homeless refugees sleeping on the streets nearby. Heartbreaking to see but not surprising in a city. 2 of the 4 elevators being upgraded, so can get crowded. Plan to wait for the lift. No laundromat in the building so washes can be very pricey. But complimentary water, soda, and Nespresso in the room.
