Attillio was a great host. He was very responsive and helpful. He picked us up from the airport and he also organized his parents to give us a lift on the way back after we checked out from the apartment. He was well prepared with maps and a list of restaurant/bar suggestions.
The flat has a great location, very close to via Etna and the main square. Amazing breakfast bars just around the corner. The fish market is literally in front of the building of the apartment, it gives a very nice vibe to your staying.
The apartment was very clean and the sofa was more comfortable than we expected. :)
Overall, I would suggest this apartment to everyone.
