We've stayed with my friends at Calogero's place for a month and it was perfect. The house is located in a peaceful, calm, and secluded area near the mountains. It has everything needed - a few cozy rooms with trees outside, few cafes and big shops in walking distance from the house, multiple hiking possibilities around. The house and the garden around it are really well cared for - both clean and full of art and places to sit with a book and enjoy life. We loved the big table outside, which is perfect for eating food together.
On top of that, Calogero was really helpful during our stay. He responded to each of our requests (like helping with arranging taxis), he provided tips and advice on various topics. He helped us make a delicious pizza in the oven which is located outside of the house. We'll never forget our time in Petralia Soprana and hope to be back in the future :)
