A truly lovely place that great friends - now in their early 80's - retired to fifteen or so years ago and live quite regally on SS and small investments in a villa of perhaps 3500 sq ft they bought.
It's about 6000' up so the near tropical latitude climate is moderated, but our friends do complain about the coldish winters. SMA is a walking town for most on the cobblestoned streets, with a beautiful Gaudi-esque cathedral, zocalo, art schools, galleries, an English library, excellent restaurants of all sorts. And, of course, unlimited photographic possibilities in the town and surrounding areas. We'll be returning next year, I hope...
