Built around two 19th century patios, this former colonial mansion positively sings with the spirit of Argentina’s proud, stately past. The enormous wooden door is hard to miss, and belies the charm that awaits within. Though the building is relatively small, the eleven rooms are spacious and quiet—each with its own unique, bright color scheme, original mosaic tiles, and unexpected surprises. One room has a clawfoot tub, while another its own spiral staircase.
