Cusco - also Cuzco or Qosq’o - is the cosmopolitan former capital of the Inca Empire, and as well as being arguably one of the most fascinating cities on the continent, it's also the closest city to Machu Picchu and the Sacred Valley. So it’s quite a busy place as far as visitor numbers go. If you like the look of our Gurus' recommendations for the best places to stay in Cusco - which include some really characterful hotels housed in converted heritage properties - then don’t hang about too long before booking!
