As legendary as its namesake sirens, this 18th-century palazzo has long set the standard for luxury in Italian hotels. It opened in 1951 with just 12 rooms (John Steinbeck stayed here while writing "Positano," for Harper's Bazaar in 1953) and now sprawls over eight floors, where extravagantly stylish guest rooms are accented with antiques and fine linens. Stunning vine-entwined terraces overlook town—the poolside terrace, the most beautiful on this coast, is the
place to have lunch. Fine Campania cuisine is also served in La Sponda restaurant, and in the Champagne and Oyster bar, contented patrons toast the good luck that brought them here. Other perks include a private yacht, loaner iPods, and a designer spa.
