The Best Hotel in Cascais and Boca do Inferno, Sintra, the Estoril Coast, and the Setúbal Peninsula

Housed in a beautifully restored 17th-century fort, the Pousada Cidadela Cascais is a real treat for lovers of art, architecture, literature, and history. The whitewashed building sits within its own artsy "neighborhood"—the Pestana Cidadela Art District—which comprises galleries, studios, reading rooms, bookstores, restaurants, and open-air art installations. The hotel itself is a work of art, with individually styled rooms showcasing colorful contemporary pieces against a cool neutral backdrop. The whole complex feels crisp, clean, and contemporary.
