Incredibly central place, just next to the "all you can get" market. Apartment was really great - we had the whole house for ourselves. There's plenty of space, kitchen with everything you need, etc. And Gaetano was AMAZING - he booked a taxi from/to the airport, organized a private tour to Etna and was all around super helpful whenever we had a question. I highly recommend this place if you're going to Catania!
