I stayed at Sabbinirica in Ragusa Ibla. It was delightful, with narrow, winding stairs to many rooms. My Classic Room had a lovely view from its tiny balcony of the Santa Domenica valley.
"The old building dates back to the 18th century even if most likely the basements predate the earthquake of the 1693. The structure consists of six comfortable and charming rooms arranged on three levels and also includes an unique holiday house."
There is a free parking lot a 7 min / 400m walk from the property. We contacted the hosts on our arrival and they drove to pick us up with our luggage and bring us onsite. Without luggage it is a short walk that includes a steep stairway.
Here are walking directions from the parking lot to Sabbinirica.
Ragusa Ibla does have ZTLs (limited driving zones) and it is easy to get turned around and find yourself in one. There is no reason to use the car while you're in Ragusa, so best to just use the free lot and come and go from there if you're taking any day trips.
