Leo is a really friendly and hospitable host, he made sure we got a parking in front of his apartment and he also gave us a map and some recommendations of what to visit in Catania. The apartment is okay, decently clean and located close to the centre of Catania so you can easily reach everything by walking. The only thing I would recommend is that you check in advance if your room has AC, especially if you're travelling in summer as the temperatures can get very high.
