Splendido, a Belmond Hotel

A former monastery turned gilded-age retreat, perched above the Ligurian coast where the yachts look like toys. The pool terrace commands the bay; the Michelin-starred restaurant serves Genovese classics beneath wisteria pergolas. This is where European aristocracy summered before Instagram discovered Portofino—and still does, in suites named after past guests like Bogart and Bacall.
