The apartment was nice and Antonino was a great host, but I wouldn't recommend this.
The place looked like the pictures, it was spacious, clean, had a small terrace and we got 3 towels each. Check-in and out went smoothly and Antonino replied quickly to our questions.
The second bedroom was a loft space without durect air-conditioning. It got really hot during the night, if we turned the AC on then downstairs it was freezing.
The main problem was the location. It is only a 20 minute walk to the center, but we didn't feel safe in the neighborhood at all.
Right after we arrived someone tried to open the lockbox and get in the apartment, but Antonino checked the security cameras and assured us that it's all right. Since we already had the keys, we didn't worry about it much, just decided to pay attention to where we are going.
Later one of our phones was stolen close to the apartment, a guy grabbed the phone while going with a motorcycle. Afterwards the police took us back to the apartment, they told us that we shouldn't walk around there in the dark.
After this our mood was pretty bad, thankfully we only had to stay one more day.
So if you decide to visit Catania, I would recommend staying in the historic center.
