I would prefer the historic downtown in Morelia although I do not know much about it yet, I will be doing a trip in the near future. If all of us interested in Morelia would join the FB group expats in Morelia maybe we could post our findings as we visit and can collectively gather more information. It has a major airport, from what I gather it is an easy drive to CDMX and Guad, 3 hours to beaches in Michoacan and the weather seems fairly close to the weather here lakeside.
