Hotel Boa-Vista
True to its name—which literally means "good view”—this hotel has eye-popping views from the rooftop pool and sun terrace of the Douro Estuary and the Atlantic Ocean. The handsome 19th-century restored convent has small, simply decorated rooms, the best of which have views of their own. An expansive breakfast is included in the room rate, and other nice touches include a welcome glass of port for every guest.
