I visited Giovanni's apartement with three of my friends and it was a really nice stay. Not just because Giovanni and his girlfriend/wife were really accommodating with the time of the check-in/out, but they also helped us finding places to visit or hang out. They also gave us a very accurate description where we can find the beach or the next grocery store. All the time we felt to be at home.
Now to the apartment itself:
The apartment was very clean and tidy up and had enough space for all four of us. Everything we needed was in the kitchen and the bathroom was also very clean.
In the future I would like to visit Mondello again and live right in this apartment.
