Pros: everything works, especially the heating in February is crucial and it worked perfectly, wifi was also fine. It's enough space for 2 persons, there is even a wordrobe. The location is perfect for visiting Catania, with a lot of amazing places nearby. There are cosmetics in the bathroom. For our convenience we were allowed to leave our luggage till the afternoon after check out. Attilio is a friendly host and responds very quickly.
Cons: kitchen is underinvested, it's hard to cook in it. Almost every night some noise was waking us up, you can hear the neighbours, but I think it's typical in the old part of a city. The main bed is too noisy. Because of heavy rain Attilio couldn't pick us up from the airport when we arrived, which was a little disappointing, becasue that's when it's needed the most.
We had a great week in the apartment and discovering Catania was a wonderful adventure :) Generally the apartment is worth it's price, except the kitchen which needs improvement.
