Santana Hotel & Spa
Taking full advantage of its location on a hill high above the Rio Ave, this modern lodging's rooms all face the river and most have their own balconies; the indoor pool and rooftop bar---both open until midnight---have similarly stunning views, too. The decor is sleek and modern, with navy and silver livery adding a touch of luxury. A wide range of massages and other treatments are available in the well-equipped spa (check the website for packages), and you can book outdoor activities such as horseback riding, kayaking, and diving. The Santa Clara restaurant (€19) offers a good selection of traditional dishes, including delicious desserts, and affords views of the eponymous convent across the river.
