Francesco's apartment - or more accurately house - is a fantastic place to stay. It was spotlessly clean, very well equipped, stylishly decorated and comfortable. The terraces are completely private and gorgeous. As many other guests have said, you are greeted upon arrival with an array of treats and drinks, which is a classy touch on Francesco's part. We never had any trouble parking on the street outside the house, though the smaller your rental car the better (which is true for everywhere in Sicily though really).
Francesco's local tips were right on point. We loved Ristorante Dammuso (excellent seafood, sit outside if you can) and Esperia Pizzeria (best pizza we had in 10 days in Sicily), both of which he recommended. Caffe Sicilian is a bit of a must for granite. When you've inevitably had enough of eating in restaurants I'd also suggest getting a (very good value) pizza from A Tutta Pizza and eating it on the steps of the Cathedral as you watch the world go by.
All in all a great experience and we'd certainly stay here again if we are ever lucky enough to visit Noto once more in the future.
