Casa do Visconde de Chanceleiros
Lovely gardens bursting with flowers, a swimming pool with views of the valley, and facilities ranging from a sauna to tennis courts are standouts at this 18th-century manor house. The friendly German owners present guests with a glass of port on arrival. This is one of the rare hotels in the Douro Valley with facilities for children, including a playground. Make a reservation to eat in the homey dining room or, weather permitting, alfresco on the sprawling terrace—local produce is showcased in the three-course dinner (€50, or €58 with wine; €5 to €25 for children, depending on age).
