Palacio Nazarenas, A Belmond Hotel, Cusco

What the classifiers highlight

A former 17th-century convent near the Plaza de Armas keeps its Inca stonework and colonial frescoes under vaulted ceilings, all 55 suites fitted with supplemental oxygen for the altitude. Forbes lists heated floors, marble bathrooms and round-the-clock butlers, plus the only heated outdoor pool in Cusco. Chef Pía León, of Lima's Kjolle and Central, runs the restaurant Mauka.
