We stayed at the apartment for 2 nights and used it as a base for our Etna South tour as it's only a 30 minute drive from where the hikes begin and you have to be there early. Irene recommended Barone di Villagrande for wine tasting and dinner which was one of our favourite places of our trip.
The apartment is very big and tastfully decorated and the bed was very comfy. Given it is the top of the chalet, the best views are from the balcony only (all the windows are velux) and Irene also says you're welcome to use the garden terraces with the BnB guests if you want.
If you want to use the jacuzzi you have to let Irene know in advance so there will be enough water for it. A good choice for a few nights!
