The apartment was perfect! It was very close to the old city center, just five minutes walk. It was exactly it's shown in the pictures, very modern and spacious.
Both Antonio and Marilyn were at the apartment to welcome us when we got there. Furthermore Antonio took me to a short old city tour to show me basics of the city.
Overall it's a great stay at Casa La Fenice. We highly recommend it if you happen to be in Catania!
