I would not hesitate to recommend Vittorio's place. perfect location, gorgeous view, cleanliness and overall state of the flat are are least the equivalent of a 4-star hotel. wish I could stay for a month!
Vittorio and his wife are lovely, very helpful, and responded instantly to any questions.
although the flat doesn't have dedicated WiFi, you can pick up the free city WiFi from inside the flat (and from within most of Ortigia.
thanks again for a lovely stay :-)
