I and my wife returned from Ecuador just three weeks ago. We visited Guayaquil (2 days) and Cuenca. We also visited Cajas Provincial Park. But mostly we spent our two weeks in Cuenca just walking around and enjoying mild weather and beautiful city. We will be back for sure.
I compiled little video and just uploaded it to YouTube. You can see it here:
