The flat is nice, it is definitely the best place to explore Catania. We stayed for 7 nights and enjoyed an interesting and vibrant Student city which is no tourist hot spot (that is rare to find on Sicily). The bathroom could have a window and the kitchen could be better equipped. Massimiliano is a really nice guy and helpful. Nearby is the famous fish market, so be brave and hunt yourself a steak of swordfish to fry! The surrounding square is great with nice restaurants, an outside bar where you can have something to drink and a nice Wine-shop, where a friendly old guy sells tapped wine from the etna region. Catania isn't scary at all. the only horrible thing is the public bus transport.
