We had a great time at Vittorio's place! It's an old, stylish house with high ceilings and plenty of space including a private courtyard. It has all the necessary amenities like wi-fi, aircon, fridge and a washing machine.
The place is 15 minutes walking distance from Ortigia where there are a lot of bars, places to eat and attractions (we were kindly provided with bikes but chose to walk). It's also close to the archeological park (probably around 15 minutes as well).
We had rented a car and it was easy to find parking in front of the entrance. There are also some shops around (5 - 10 minutes) just make sure you avoid 'siesta time' when they are likely to be closed.
It was a pleasure communicating with Vittorio and his dad, thanks so much for having us!
