We really enjoyed our stay at the apartement, which is beautifully and thoghtfully equipped. Giovanni's tips were all wonderfull! He and his wife are very nice and open people.
Catania is a good starting point for visits to several places on Sicily (Valley of Temples, Villa Romana, Etna, Taormina). If you want to visit the beach or lie at a pool I would suggest to add some nights in some hotel or near the coast after staying in Catania.
