Welcome mocktails and snack platters, stocked minibars and cooked-to-order breakfasts all come as standard at the Casa San Augustin. Guests can hop on free loaner bikes to explore Cartagena, laze on the rooftop terrace’s rattan loungers or read a book in its library. Made up of three colonial-era buildings, the boutique hotel has retained its original architectural features. 30 bedrooms have Ortigia toiletries and shuttered windows; some have private patios and plunge pools, while the Suite Del Virrey boasts two rooftop terraces and an outdoor Jacuzzi. And a secluded courtyard accommodates a foliage-flanked heated freshwater pool.
