"A dedicated national monument dating back to 1592, this former monastery sits on Inca stone foundations, which were later topped by plenty of Spanish colonial flourishes. Evidence of the hotel’s history is everywhere you look, from the rich fabrics and antique furnishings to the 18th-century paintings that decorate the public spaces. The 125 rooms and suites feature original design elements, along with perks like butler service and free Wi-Fi. Many are even enriched with oxygen to help combat the effects of Cuzco ’s dizzyingly high altitude. The Illariy Restaurant, overlooking the serene courtyard, is ideal for a leisurely breakfast, while the Lobby Bar is the spot for a late-afternoon pisco and live jazz around the fireplace. Though the central Plaza de Armas buzzes just a few blocks away, once you’re through the hotel’s arched doorways, you’re in another world—and century."
