The five-pearl Areias Do Seixo Charm Hotel & Residence is an excellent choice for couples seeking romance and privacy. The 14 large, rustic-luxe rooms have patios, fireplaces, and open-floor bathrooms, but lack TVs, minibars, and air-conditioning. Property features include a spa, a striking infinity pool, private beach access, a restaurant and bar, and weekly outdoor activities. But travelers should be aware that the remote location means there's little off-site of any interest, aside from the area's sweeping natural beauty. There aren't many similar properties, however, Palacio Estoril Hotel Golf & Spa might be a good alternative to couples wanting a luxurious experience with a gym and golf course.
