Finca Rosa Blanca is an eccentric architectural gem surrounded by the green, lush hillsides of a coffee plantation. A turret tops the main building, and arched windows, walls of glass, and curves instead of corners are at almost every turn. Throughout, the glow of polished hardwood blends with white stucco walls and brightly colored murals. If breathtaking bathrooms are your idea of luxury, splurge on the Rosa Blanca suite, which has a stone waterfall that cascades into a tub in front of a huge picture window, and a spiral staircase that leads to the top of the turret. All the suites and villas have the same sense of creative luxury, with beautiful tile work, fab views, and other design touches. The restaurant and spa here are top-notch, and the owners have a real dedication to sustainable practices. The in-house coffee tour is terrific.
