The Ritz
If you're wondering if the Downton Abbey–style world of the old British upper class still exists, look no further than here; The Ritz is as synonymous with London's high society and decadence today as it was when it opened in 1906. The central lobby, with its chandelier and sweeping balconies, is as photogenic as any in London. The lounges are as gorgeous as ever, and the bedrooms are bastions of Louis XVI style, with acres of luxurious fabric and glittering chandeliers. With a ratio of two staff members to every bedroom, you're guaranteed personal service despite the hotel's massive size. Note that the Ritz is still committed to the ancient regime of English manners, and the dress code remains inflexibly strict—woe betide a gentleman if he doesn't wear a jacket. The staff, however, are incredibly polite and courteous, particularly the concierge who stand smiling outside, ready to open the door for those visiting for afternoon tea.
