Hotel Café Royal

Why We Love It: Per its name, the pièce de résistance of these posh digs is the copper-domed rotunda that encircles the suite and is an original feature of the historical building. The furnishings reflect the smooth curves of the open-plan space and include a crescent-shaped sofa and a rounded-edge mint-green marble freestanding tub. The suite has an oversized mirror ball with a spectacular LED lighting system and a DJ sound system with concert speakers that transform the suite from serene and relaxed to party ready. Also not one, but two terraces, offer unparalleled views of London icons such as Piccadilly Circus, Westminster Abbey, and Big Ben.
