We had a great stay, especially because the location is stunning: you'll be waking up and going to bed listening to the sea, and just staring at the sea was very relaxing. Be aware that sometimes it can get a bit loud since there are a few bars and restaurants nearby but it wasn't a deal breaker in our case.
Check in and check out were flawless and everything in the apartment was clean and functional and would definitely book it again if I traveled to Ortigia.
