I hope you also got to try a pisco sour!! I think that's the real national drink ha ha

Cusco is a magical place, good to see this article about it. I lived in Pisac for two months, in the Cusco region, and also spent maybe 6 weeks in cusco itself, mostly around San Blas. I hope you got to see the Saksaywaman ruins, you can walk there from the San Blas plaza in about 20 minutes. Lots of people miss it because they don't find out about it, but it's right there! You can see a few temples there for free, or pay to see them all, I never paid but used to walk up there in the morning for exercise. The moon temple you can get to for free, and also can see the main ruins, but up close you have to pay.
