The best part of staying at Arianna’s was probably Arianna herself. She was super friendly, super nice, incredibly accommodating despite us arriving about 2 hours later due to some kerfuffle with buses. But honestly, the 20 minute walk from hers to Centrale is incredibly doable.
The apartment is right in the centre of town. It’s almost ridiculous how close it was to everything of interest in Catania.
One of the best AirBnB’s I’ve stayed in, and I would highly recommend it.
