The first thing you see when you walk into this hotel, which is situated right around the corner from the Plaza de Armas, is a stunning piece of artwork behind the reception desk made of 6,000 pieces of Swarovski crystals, an homage to the Incan sun god Inti. The 16th-century convent, constructed over an Inca foundation, is a virtual museum where Inca walls are exposed under glass, as well as pre-Inca artifacts found during the excavation of the site. Most rooms overlook a stone courtyard, with some suites having private patios or looking onto centuries-old stone walls. The modern decor gives subtle nods to the Inca and colonial past, while the marble bathrooms have both tubs and rain showers. Oxygen can be pumped into the room to help with altitude sickness for an additional fee. A huge basement spa features an indoor pool, plus a full range of signature treatments.
