Located in a beautifully renovated colonial building, the 32 room El Mercado Tunqui is now the Cusco hotel of choice for hikers embarking on the Salkantay Lodge-to-Lodge Trek to Machu Picchu.. The hotel is just a short walk from the Plaza de Armas, Cusco's main square allowing travelers easy foot access to a variety of restaurants, shops and cafes while being far enough away from the busy square to provide a quiet and restful sleep. .
