We stayed at Anna's house for 6nights. Sadly we didn't get to meet her in person as she was in Rome visiting their daughter. But Pietro made it up for her. The was the must perfect host you can imagine. He showed us around ( we saw an oil mill and tasted wine in his cousins vineyard), made us try Sicilian food and invited us at his place. We slept in their farmhouse, located in the valley near st Pier Niceto. The beach is close, supermarket as well. The house is a small two room cabin, simple but perfectly equipped. The garden is amazing and the spacious terrace is perfect to just relax.
I really recommend a stay at Anna's and Pietro's place if you want to get to know Sicily.
