Six Senses Douro Valley
This cutting-edge resort in and around a 19th-century mansion just 8 km (5 miles) from Lamego has helped the region brush up its image as a fashionable destination. Contemporary architecture is offset by traditional decorative motifs in subdued creams, grays, and browns. Outside, wooden decking around the pool enables you to revel in the spectacular hillside setting. Inside, the huge spa has a heated pool, two saunas, steam and ice baths, and 10 treatment rooms. The 24-hour gym has updated equipment and a packed timetable of fitness classes. There are two villas, each with a private pool, and nine rooms in a separate house sharing another.
