Nice apartment with good location. Fish market, cathedrals, central square, bus station (with a 15 min to the airport) in 5 min walking distance.
Central railway station (Catania centrale) in 1.5 km which taken 10 min.
But pay attention if you traveling with children apartment is a little bit cold and damp in autumn.
So thanks a lot to Daria E Stefania for the hospitality
