Our stay was very good, Letizia and Salvo are very nice hosts accomodating our requests. They were very responsive and flexible (for example we were requesting extra pillow which they provided). The flat is really at the heart of Catania, 2 minutes walk from the Duomo, FishMarket, great restaurants etc. The apartment is very cute, just enough for a couple, full with amenities. One consideration for someone who's sensible to sounds - this is downtown, full with bars, so you can expect some sounds from the street late night. But after a tiring trip to Etna you'll have no issue to sleep :)
