Steeped in history and bursting with character, Casa San Agustin is a serene oasis in the heart of Cartagena's atmospheric old town. The hotel's heritage as a former convent can be appreciated in details such as the lovingly preserved frescoes in the library and the tranquil cloistered terraces. Remnants of a 300-year-old aqueduct intersect the property, and the feel throughout is one of an enchanting labyrinth of cooling terracotta, trailing vines and intriguing nooks scattered with local artworks and artefacts.
