Paolo was very nice and friendly and super responsive and communicative. He gave us great recommendations of places to visit.
The apartment is amazingly located in the center of town near lots of restaurants, coffee places and shops.
The apartment itself is a little old but well kept. There are quite a few steps to walk up (3-4 floors) this is something very important to consider.
our visit was in the winter, there's air-conditioning (heating) in most rooms. however you have to be cautious about how many appliances you have on as the electricity is old.
We had a very pleasant stay and visit to catania.
