We stayed in a fabulous, comfortable room and were well looked after by our host, Teresa.
Main sites are easy walking distance, as are a wide range of bars and restaurants. The B&B is on a pedestrianised street so you don't have to worry about noise even though you're central (there are only three or four bars on the whole street, they don't attract a large or raucous crowd and they close promptly).
Breakfast was lovely and served in Teresa's beautiful kitchen. Teresa and her husband also very helpful with advice re excursions, restaurant recommendations and taxis etc.
Will stay here again if/ when we return to Catania.
