We spent three nights before our trek and a night after at the Casa Andina San Blas. The staff arranged a taxi tour of the Sacred Valley for us, called and got our treking duffles delivered, stored our luggage, and went out of their way to make us comfortable and our time in Cusco pleasant. The ample free breakfast was appreciated. The location is great. There are a lot of good restaurants nearby and the artsy neighborhood is fun to explore. The walk down to the plaza area was easy and made us even more appreciate our quiet neighborhood.
