We've spent more than a week here and had a good time. Sternatia is a small and very quiet village in the middle of the Grecia Salentina. We stayed here because my wife was working close by in the area. Although the village has not much to offer, you can easily explore the region from here as all the major sights are not far away. You should have a car though. Still, there are good bikes (also for children) you can use.
Valentina was very friendly and helpful. Every morning she made breakfast and gave us informations about her town and Salento. We only had some minor issues with the WIFI and the shower in bathroom, however, she was always very fast to find a solution. She is also taking good care of the place. So especially if your are interested in the Grecia Salentina this is a good place to book.
