We had a nice stay in this Airbnb. It has a nice sunny balcony and most things you need. Communication with Sara was good and check in was easy once we found it - Google maps sent us to a different flat a few metres down the road.
It's not so close to the centre of Catania and there isn't a regular bus service, but we hired bikes from Zeronove near the station which provided a lovely service and good bikes for a good price. Also recommend cycling north of the city to Aci Castello, Acitrezzo, etc.
There is a nice spot near the apartment by the sea called 'Lo scoglio del gabbiano' where you can chill on the rocks and dip your feet in the water.
Overall, we can recommend this place for a mix of the city and the smaller towns surrounding Catania.
