Three recently opened hotels offer travelers new ways to experience the Andes. La Casona Inkaterra, Cuzco | Location: A block from the historic Plaza de Armas, the latest carbon-neutral property from Peruvian hotel group Inkaterra is secreted behind a massive green door on tiny Plazuela Las Nazarenas, which it shares with the famous Hotel Monasterio and the Museo de Arte Precolombino. Details: It may be a sprout to Monasterio's beanstalk, but this discreet hotel's intimacy and dazzling restoration will make smaller-scale luxury the new Cuzco standard. The 11 rooms of the former conquistador's mansion have views of the plaza or open onto a charming courtyard. Crisp yet cozy, the suites nod to both Incan and colonial influences with antiques, handwoven blankets and traditional thickly plastered beams crossing the high ceilings.
