The apartment is GREAT! It is indeed located very close to one of the best beaches in Ortigia (on weekends, better get there early). The apartment is clean and well kept (the shower booth is small - but it's fine). The A/C works perfectly and the WiFi is super fast. Paolo is a responsive and helpful host and generally speaking, we had a good experience.
That being said, we feel it is important to mention that the apartment is located deep in a Limited Traffic Zone, which basically means you simply CANNOT park within a ~1.5km radius. Therefore, if you are only planning to visit Ortigia (preferably without a car) - this place would be a GREAT choice. But if you have plans to drive around other parts of Syracuse and get back here (like we did), be prepared to park and walk...
