Pestana Palace Lisboa
An overnight at Italian architect Nicola Bigaglia's 1904 Valle Flor Palace—now a national monument—is like Night at the Museum. The decorative details are ravishing: Original frescoes, antique paintings, precious stained glass, and rare exotic woods dot the 189-room property in Santo Amaro; while public areas like the chapel, the French-style saloon with exquisite red velvet inlaid chairs, and the stunning pool (a former aristocratic lake) offer delightful distractions. Classic rooms with balconies offer views over the hotel's Versailles-like gardens (also a national monument). One other highlight: the roasted-vegetable gazpacho served at the restaurant.
