We have stayed for entire week in Catania. Lorenzo's place is located in a perfect location, just 5 min walking from the main square (Duomo), from the Fish market. There are many good restaurants around also just 5 min walking. Trip from airport took us 10-15 min by taxi.
The apartment is really big! Two big bedrooms, main room, with air conditioning available in every room, and a very nice patio just outside. There is also a suitable bed for kids.
The place has absolutely everything you need, and Lorenzo is answering on all questions really fast. No other words except my full recommendation to stay at Lorenzo's place.
