This was one of my best Airbnb experiences in many years! The house has everything and more for a worry free stay. We really enjoyed coffee and water left for us.
Others mentioned the steep stairs, so if it's not a problem for you then you're in for a treat. You can enjoy the beautiful view of Etna out of every window and when you reach the terrace the view is straight out of a fairytale! We did yoga there every morning and drank our coffee looking at Etna in all her stunning moods.
But Vincenzo himself was by far the best part of our Airbnb experience. He helped with all our questions, kindly provided information about transportation in the area and recommendations on things to do in Castiglione di Sicilia. An absolutely fantastic host!
I recommend Vincenzo's place wholeheartedly and will be back there myself as soon as I can!
