Thank you so much Donnamarie. The apartment was perfect, clean and full furnished. exactly conformed to Donnamarie's description.
When reading commentaries, it seems like the apartment is very far away from town with a huge walk etc.. but actualy it is not that bad. Yes, there are stairs, a few. But walking down and up was not that hard and permit us to eat pizza and pasta as much as we wanted haha. It's was 7 min down and 15 min up, which is not that bad, with a perfect view, on the Etna, the ocean, and others town. Waking up and having breakfast on the balcony was just amazing and so i recommende this location if you want an amazing view, quiet apartment, but still have the opportunity to walk to the main street when you want !
