Forget oceanfront — the Hotel Ristorante Grotta Palazzese is closer to being ocean-top. Set on a cliff overlooking the Adriatic Sea, this small luxury hotel gets its name from the sea cave that lies at its heart. Inside the cave — which has hosted local nobility since the 1700s — you'll find the hotel's summer restaurant, providing some of the most romantic ambiance around. In the fall, the Sea Lounge offers up panoramic views of the sea, and you'll also find a bar and lounge, a sun terrace, and 25 rooms on-site, which offer views of either the sea or the streets of historic old town.
