Really great place to stay in Catania. The apartment is really nice and spacious. The location is close to the famous fish market and in just max 5/10 minutes walk you will find a lot of bars and nice restaurants. Try the granita at Comis Gelateria. Eat pizza at Osteria dei Pazzi and have a drink at Il 17 ( just at th end of the apartment's street). Of course for fish and seafood the fish market is terrific.
Ah I almost forgot...sicilian people are sooo nice. Enjoy your vacation guys!
