The apartment is very well located on Piazza Federico di Svevia, allowing to reach the market and the centre with plenty of restaurants just by walking 5-10 mins (plus all the restaurants directly downstairs). Unfortunately, this great asset also meant incredibly loud music coming from the piazza, both during the Ursino Buskers festival taking place on the weekend but also the previous night, due to live music played at the restaurant downstairs.
This didn't allow to keep the windows open, which led to the next main issue: the apartment gets very warm during the night, in spite of the AC kept running.
On the positive side, it looks exactly like in the pictures: it was clean, neatly arranged and well designed. Sonny, who let us in for the check-in, was very communicative and friendly and gave us plenty of tips for both Catania and the areas nearby. He was also very fast and responsive when we found some ants in the carpet one evening and came the next day to check what the issue might be.
Overall I would recommend it for someone looking to explore Catania at its most authentic, provided that they can deal with a lot of noise and very creative parking.
