We had such a good time at Petra's! The location of her property is absolutely spectacular as you get excellent views of both Etna and the Catania coast. Petra and her staff are lovely and were so welcoming.
The guest house was very clean and equipped with everything you need for a short stay, including a comfortable kitchenette for preparing simple meals. The accommodation is equipped with a fan for the summer and a woodstove for the winter but understandably, there is a small charge for using these. Having said that: We stayed in the first half of October and was a little chilly already but we found we didn't need to heat as the duvets provided are pretty thick.
If you can ride, you should absolutely book a horseback ride! My partner is still a beginner but Petra and her staff took fantastic care of him and the horses are gentle and well-mannered - plus they are well-cared for and live in a horse-friendly environment.
