We had a great time in Catania while staying in Grazia's apartment.
Grazia was really helpful and the apartment is located very close to the best parts of the town center. We really enjoyed diner in restaurants Grazia recommended in a selfmade brochure we found upon arrival.
As a tip we'd like to recommend buying a mosquito net for above the bed and one for in the door. This way you can breeze some fresh air through the apartment without having to worry about moquitos and if there are still any, they won't bother you in your sleep.
Thanks a lot Grazia, and all the best!
