Firstly, if arriving by car make sure you have a small one! We had a Fiat Panda which was fine for manoeuvring through the narrow streets and parking but anything bigger would have been "interesting"! Secondly there are quite a few steps up from the main strip of bars, shops and restaurants, not a problem just be aware.
Antonio's place itself was great, nice and big and close to the town in a quiet area and we parked righted outside! Air conditioning was a boon too and we liked the funky front door key. The area of town was a bit grubby, I think the wind had blown rubbish through the back streets and it hadn't been collected but it turns out this is not uncommon in Sicily. The apartment itself was lovely and clean.
Antonio's communication was great, he even kept us updated with the progress of a last minute plumbing job that needed doing the morning of our check in. It wasn't a problem and Antonio met us at the flat and helped with the final directions and parking.
All in all we really enjoyed staying here, thanks Antonio!
