We had a fantastic 3 days in Catania at Giovanni's place. He was very chilled out and made sure we had no stress during our stay.
The apartment is exactly like the photos - very charming. You can understand why there is so much demand for that place.
Giovanni welcomed us with a nice 15 minute sit down, explaining what to do in Catania and preparing some printed maps and guides.
I would happily stay here again!
