No. 11 Cadogan Gardens
Located near Hyde Park, this 58-room family-run hotel consisting of four adjoining townhouses is outfitted in Louis XV-style furniture and sparkling chandeliers. During your stay, pretend to live in an old-fashioned world where tea is served at 4 p.m. by a butler, but enjoy contemporary luxuries like large bathrooms, plasma-screen TVs, and free Wi-Fi. Seeking discretion? Book the Garden Suite—it has a private entrance.
