Grand Hotel Les Trois Rois

"This 1844 grande dame on the banks of the Rhine reopened in 2006 following a 20-month renovation, and again became the most prominent address in town—the place to gossip over espressos on the riverfront terrace, to broker business deals in the firelit bar, to throw lavish dinner parties among the silver rose bowls and candelabras in the formal restaurant, Cheval Blanc. The 101-room hotel isn’t an exact restoration but rather a tribute to the sumptuousness of Belle Epoque grand hotels, with heavy wooden doors that glide shut, chandeliers bigger than most men, and marble columns crowned with gold. Guest rooms are just as nostalgic—especially those in the 1904 Art Deco wing—but still manage a few discreet modern touches (Wi-Fi, heated bathroom floors). The service is flawless, from the tuxedoed waiters to the housekeeping staff, who at turndown leave behind pitchers of water, chocolates, and—surprise!—kiwis. By the way, on weekends, room rates can drop by almost $200."
