Angelo is a caring person, he welcomed us personnaly and gave us a lot of informations about point of interest in Catania. He's easy to contact (we used Air BnB or WhatsApp).
He's BnB is in the center of Catania, very close to a lot of points of interest, close to the bus terminal (for exemple to go to the airport) and at about 20 minutes (walking) from the central train station.
We really enjoyed our stay and we can only recommend you to stay at Angelo's BnB.
