Para Air bnb: Valeria is a very friendly host: I could enter the apartment early and she gave me a lot of practical tipps (what to visit in the city,how to go to the beach, etc) The apartment is functional but has everything you need (bed, douche and a small kitchen)
The main reason to chose this apartment is its location: you are at 5 mins by feet from the bus to the beach and at 10 mins from the historical center (duomo, fishmarkt etc), so really a perfect starting point to get to know Catania ! (without being active part of the rather intense traffic :-)
