Prompt communication, Attilio and Elisa gave very detailed instructions for how to check myself into the apartment, and were quick to respond whenever I needed help with anything. Attilio also taught me how to get from the airport to his apartment! The apartment is perfectly located in the fish market and a stone's throw from the Duomo, like others say it's quiet despite being in such a central area. It is clean, and the bed is very comfortable. I'll definitely be looking to stay here again the next time I'm in Catania!
PS: and the restaurant Vuciata downstairs is just incredible too.
