Apartment is really great to explore the Sicilia on your own. We stayed here for 4 days during which we traveled to Taormina, Palermo and Siracusa. It is really close to the main bus and train stations so you can easily travel to other cities while having all your luggage in your apartment.
It is not so close to Catania city center but everything is just fine and you are at city center in 20 minutes by walk.
Apartment was really big and had everything we needed to enjoy our roadtrip to the fullest. Only thing what was not so great was the air conditioning since it didnt provide fresh air to the bedroom upstairs but everything else was amazing. a lot of space for everything and kitchen is also very well equipped to cook food.
Overall, very great experience!
