Hotel Excelsior
Maharajahs, emperors, and Hollywood legends have stayed at this grand-tradition Chiaia seafront outpost, which opened in 1908 and has an interior that's a symphony of soaring columns, gilded French doors, and Venetian chandeliers. 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 rooftop bar and restaurant, with its sweeping bay views.
