The room was nice and clean. The communication was quick and helpful, and the staff at the reception was very nice and always wanted to make sure we have all we need to have a nice stay. AC saved our lives during hot Sicilian days! :)
It was possible to park the car on the street for free. It took us about 15 minutes to walk to the historical centre. If you want to spend some time by the beach, I recommend renting a car as the city beach might be crowded. It is a nice place to stay if you plan to visit Siracusa for a couple of days, for a longer stay I would recommend some more spacious accommodation (with a separate living room and bedroom). But it is my personal preference.
Overall experience was very pleasant and I highly recommend staying at Fabrizio's place!
