Maharajahs, emperors, and Hollywood legends have stayed at this grand-tradition outpost that opened in 1909. The exterior, with the hotel's name magnificently picked out in Pompeian red, is awash in elegant detail, and the interior is a symphony of soaring columns, gilded French doors, and Venetian chandeliers. These days the hotel caters to corporate chiefs, and its ballrooms host company meetings. Discreet but attentive service is the goal here—if you want to hire a yacht, the concierge will oblige. After a day of sightseeing, repair to the peaceful piano bar, where the barman mixes the driest martini in town—ask for a Hemingway. The restaurant La Terrazza, dressed up with antique red accents and vermeil tableware, serves first-rate food, and the terrace with sweeping bay views makes summer dining a memorable event.
