I've never met a host who is so kind and thankful because you stay in his/her apartment. Claudio was happy to provide us every information we needed. Moreover, he even offered to drop us at the airport in the last day.
The apartment is lovely and cozy and unique by its design. The accuracy of the description on airbnb and the reviews you read are true. The apartment is very clean and you have everything you need here: from washing machine, which it's working perfectly, to kitchen equipment and so on. The location is very good, very easy to find if you come from the train station (around 15 minutes by walk) and 5 minutes walk to the center. You have restaurants nearby, shops, grocery shops, pharmacies so basically, it's the best place where to stay when you are in Catania.
I warmly recommend Claudio's apartment. Trust me, you won't regret it! :)
