“Best hotel staff in Cusco!”
Casa Andina San Blas is a lovely hotel, great location, good rooms, and a beautiful courtyard. The best part of all is the staff - our bags were delayed arriving in Peru, and the hotel staff spent countless hours on the phone with Delta, American Airlines, LAN, and the Cusco and Lima airports to try to track them down. It took 5 days, but without the Casa Andina people on our team (we don't speak much Spanish), I'm not sure we would have ever got them back.
Only downsides: very low water pressure in the showers and toilets are a little dodgy.
