Our group of 5 people had a very nice stay. The flat is huge and well equipped. Its location is great for exploring Siracusa, since it's kind of in the middle of the different landmarks. The parking space was also a great addition. The street it's located on is very busy, though.
Onofrio was very nice and helpful. He and Gabriella helped us out, when we got a parking ticket before our departure, that we couldn't pay right away, since it was a holiday, so we are very grateful for their assistance.
