We can only highly recommend to stay at Paola‘s place when you are in Catania. The apartment/house itself is perfectly located (close to most of the great sights as well as the harbour but quiet enough to have a good night of sleep). The whole place is very nicely furnished and equipped (since there is no washing machine you can use the laundry service around the corner which is not expensive and very fast).
Paola is by far on of the best hosts we had on Airbnb. Not only did she provide loads of helpful tips where to go to, what to see and where to eat (all of which were then affirmed by other locals we met or knew). Paola also was super helpful throughout our stay, checked in with us to see if we were all good and booked as requested a tour to Etna for us with really nice guides (we were picked up at the apartment).
We would stay at Paola‘s again for sure.
