This past November, we spent a week in Akrotiri on the southern part of Santorini. Very relaxing and quiet location, far from the crowds of Fira and Oia, although even in those popular cities, the crowds were not so large at this time of year. Oia may have the best sunset viewing, but we found the sunsets splendid throughout the island. Not much infrastructure down in Akrotiri but there is a decent grocery store, a handful of tavernas for cold beers and tasty meals, and plenty of walking opportunities. A half day sail to view the caldera from the water was a great break from walking and eating.
