Old world glamour holds sway in this famed waterfront hostelry that pampers the rich and famous and provides a Grand Tour–worthy experience (with all the 21st-century amenities, including a spiffy spa and small indoor pool). Expanses of shiny parquet, handsome old prints, fine linens on the firm beds, and classic furnishings give the large, bright, and very comfortable guest rooms sophisticated-yet-understated polish. The big perk, though, is the view of the bay, the Castel dell’Ovo, and Mt. Vesuvius outside big glass doors that open to balconies off many rooms and suites. You’ll get the same eyeful from the bright salon where a lavish breakfast buffet is served and from the rooftop restaurant. High-season prices are geared to the pocketbooks of celebrities and dignitaries, though off-season rates and the occasional special offer brings the memorable experience of a stay here within reach of the rest of us.
