This apartment was comfortable, clean and convenient. In terms of location, you are right in the middle of all Catania's sights. It is right by the Duomo and literally directly over the fish market and produce market.
Gwendalina and her staff went above and beyond to get us checked in and comfortable at the apartment.
The one thing for future guests I would recommend would be a good pair of earplugs. The market gets started early, you'll want to make sure it doesn't wake you up at 5 in the morning.
