We had a very nice time in Catania.
Andrea and Baiba were super friendly and gave us lots of great tips before we arrived. They recommended some great restaurants and sights. When we arrived it was exactly as described in the pictures. They also gave us a good Sicilian wine on arrival. When we asked questions, we got an answer within 5 minutes. Even after we left for another city, we were kindly offered to contact them if we had any questions.
The Airbnb is definitely recommendable for a comfortable stay.
