Carmelo is an awesome host. Couldnt have been more helpful or kind. We really appreciated him setting up an early morning cab to the airport for us. His apartment is in a great area, close to coffee, food and the metro to take you to the old scenic part of Catania. I would highly recommend having a working phone or some way to be in touch with him as he'll have to meet you at the apartment or pick you up.
The apartment itself is cute and tiny. Worked great for a couple, might be a bit too tiny for more people especially with big luggage. Felt really homey though and had everything you could need. Few little quirks with the lighting but no big issues. Great working air conditioning. Do note the ceilings are really low. If you are above 6'2 you might be a bit uncomfortable. Also note that it is a walkup of 3 staircases to get to the apartment if that's an issue. Overall, we had a great stay at the apartment. Especially with awesome host Carmelo's help along the way.
