Antonio is a really nice guy. He was so kind to pick me up from the airport. The apartment is just as shown on the picture and as the description says. It was perfect for my stay. And it was very clean. He also provided my with some bottles of water and a few products for an Italian breakfast.
The apartment is located in a residential area, but within walking distance to the bus and train terminal, the city center and main attractions. Close by are a lot of small grocery stores, bakeries, restaurants and supermarkets.
When I come back to Catania, I will definitely book Antonio's apartment again.
