You simply cannot find a better Airbnb at this location. Add onto that a very reasonable price and this is truly one of the best we've ever stayed at. Let me break it down:
Location: At the northern tip of Ortigia directly overlooking the Apollo ruins and a main public arcadeway. At the doorstep of a large everyday food/apparel market, loads of restaurants and shops. 5 minute walk to the big public parking lot. In short: Perfect.
Unit: We stayed in the upper level which was spacious, thoughtfully decorated and very interesting architecturally. Powerful, efficient A/C in the main bedroom, with comfortable mattresses/pillows and well stocked linens and extra blankets. Fully equipped kitchen with some welcome snacks and water. Bathroom had a gorgeous clawfoot tub. Only minor gripe is the shower curtain was not waterproof and it was hard to keep water from leaking all over the floor.
Host: Nicolo was great with timely, helpful responses to our questions and requests. He greeted us at arrival, acquainted us to the city and apartment and gave us his contact info. Just the right amount of friendly but not overbearing.
So if you are lucky enough to find this Airbnb available do yourself a favor and book it without having to worry.
