Marco is a very pleasant guy, he let us check-in super early and was very responsive the whole week we were staying in the apt.
The place is clean, everything is good. Outside there was a bit too loud, but... you know.. Italy :) If you can't stand anything else but silence, it's not the country you want to go to :)
The area is also very good. For the first time, we were not sure about the area, but then we realized that this is the area where it's still almost a center of the city, but it's completely free of tourists. We even thought maybe it's just not a popular time of the year, but then we walked 5 mins towards the center and realized the city actually is full of tourists.
The building is historical (it's not a surprise for Catania), which means it's old, which means certain cons, but c'mon, it's gorgeous).
So, for us, it was very nice place in the very profitable location.
Oh! Marco even made prints for you with places to go in the city and outside) Very nice of him :)
