Marco's apartment is cozy and very clean, although the pictures already show it's not the biggest. The terrace is shared with the rest of the house (access through yard and staircase) and absolutely breathtaking - plus, it included a visit by some friendly neighbourhood cats for us.
The location inside the city centre means you can walk anywhere in just minutes, but light sleepers should be aware it also means traffic thundering down the small alleys at all hours.
Marco himself is super friendly, accommodating and quick to communicate, and his tips for lovely local wining and dining made our time in Catania extra nice.
