Palazzo Margherita, owned by Francis Ford Coppola, located in an unconventional town called Bernalda. The Hotel was designed by Jacques Grange, another reason for me to visit it, and it's authentically old school Italian. It's not in a very touristic town. This is a place more in tune for people who want to experience the real Italian small town life, but even if there is not much to do, I would be perfectly content drinking Margarita's by the pool or simply walking around the town and enjoying the beautiful medieval hilltops.
