It is the most unusual place and I really felt like I was in another world, even another century.
The altitude made me feel odd but it was the small cobbled roads and ancient cathedrals which really felt out of this world.
If food's your poison there are restaurants to die for with menus which really push the boundaries, great wine lists and delicious cocktails - all at very cheap prices.
I thought Cusco had the perfect blend of old and new. It's very ancient and beautiful but really cosmopolitan at the same time.
And it was in Cusco where we booked a tour of the Sacred Valley, a day at Machu Picchu and four days in the Amazon jungle. There were exciting times ahead.
Next stop: Being left breathless in Machu Picchu.
