We were welcomed by Salvatore's father, Alfredo, who is the loveliest man. It was an incredibly warm welcome, especially considering we arrived rather late.
He was very reactive to messages and had great suggestions.
The apartment was impeccably clean and very comfortable. My friends and I particularly enjoyed how spacious and well equiped the apartment was, the big terrace and the private parking space as Aci Castello is really sloped (bottom of the Etna).
I would definitely recommend staying in Salvatore and Alfredo's Airbnb, especially for families!
