Casa San Agustín, Cartagena, Colombia
This dreamy oasis (reminiscent of a sophisticated Moroccan riad) is pretty special indeed with 31 rooms and suites set across three lovingly restored 17th-century colonial homes, unique ancient Spanish aqueduct wall, and Cartagena's most Instagrammed pool. Luxurious, charming, and packed to the rafters with history and old-world charm.
