We had a wonderful stay at Giulia’s place. The location is extremely scenic and serene with views of both the sea and mount Etna. The house is located on a hill and is surrounded by vineyards, fields and farm houses. The house itself is spacious and comfortable, with a large well-equipped kitchen. The location is somewhat secluded, and you definitely need a car for everything including grocery shopping but the setting is beautiful especially in sunny weather. I can only mention a couple of things, that might be worth knowing for future visitors:
1) The road leading up to the house is not paved and in sometimes, especially if it rains, can be difficult to reach due to a large number of rocks on it. Even with a small car we had some trouble and scratched one of the wheels. It's probably ok in other seasons, but we had some trouble in end of February.
2) The house is heated by firewood which gives it extra charm. When it's cold, it requires a little bit of effort to keep up during the day. Also, it's worth noting that the weather in Zafferana is quite different from coastal cities in Sicily (e.g., Catania), so please prepare accordingly.
Overall, we would highly recommend Giulia's place, especially for those looking for a scenic retreat and a good base to explore Sicily.
