Carved out of a cliff opening overlooking the Adriatic, this hotel rests amid rocks and grottoes that have wowed onlookers for centuries. The property's tour de force is its summer restaurant, which sits on a natural bridge inside a sea grotto surrounded on both sides by water. Diners nibble on impeccably prepared fish while waves below cast blue-green shadows on the grotto walls. It's one of the most romantic settings in all Italy. In winter, guests dine in a restaurant atop a high cliff overlooking the sea.
