Marcello and Claudio are great hosts. They have been there for any questions at any time. They have also set me up with trips, recommendations and reservations when I asked them.
The appartment is nice - perfectly located in the center of the city and in the middle of the bustling nightlife of Catania. Just make sure you don´t mind climbing up stairs. It is on the top floor of the building. And the appartment itself is on 2 floors as well - so you definitly get some exercise in during the day just going to the bathroom :-)
