Greece
I saw this many years ago on a Minneapolis winter afternoon, and walked out into a snowy, icy grey day. I vowed someday I'd go to Greece. A year and a half ago I finally did, spending 2 weeks in Athens and the Pelopennesian Peninsula. We didn't get to Mykonos, where this was filmed (and which I have been told is a lot more commercial now than in the film) but my husband and I loved Greece so much. It's incredible how gorgeous the Mediterranean is there, and how nice the people are.
I saw this movie again today for only the second time, and watched it with my husband this time. We really enjoyed it. I especially liked the ending, which I didn't remember from before. It leaves open the possibility that her husband might be re-habilitated by the island, and learn to laugh again. It was also funny that Costas decided to clear out before he arrived!
