I would book Santos place again!
The apartment is directly in the city center of Catania, and you can reach everything by feet.
I also want to mention that the apartment was very clean and Santo helped us with a lot of recommendations of places to visit and eat. He also helped us figuring out the public transport in Catania.
At last Santo also let us leave our luggage in his place that is secured with cameras so we could spend the day longer in Catania after the Check Out.
Thank you so much Santo for this nice experience :)
