Stayed with our two year old son for two weeks this August.
The apartment was exactly as described, very stylish for a small space. Our hosts were extremely welcoming and there were many thoughtful touches that stood out - basic cooking ingredients, drinks and fresh fruit and pastries were all stocked up on our arrival! The apartment itself is clean and well-equipped.
The location is excellent - about 15 mins walk from the main square and historic centre of Catania. There is also secure parking available, as well as parking on the street.
The only reason I have given four stars instead of five is that we had some problems with the electricity - were there at the very hottest time of the year and sometimes the electricity couldn't cope with multiple air conditioners. However this was easy enough to work around, didn't cause any long-term issues, and our hosts were very quick to respond when we contacted them to report it.
On the whole I would happily recommend it to anyone wanting to stay in the centre of Catania.
