Pros - Incredible location in the centre of it all with everything you can want within easy walking distance. Very clean, exactly as pictured (although smaller) and has everything you should need for a short stay. Communication was great prior to check-in and Manuel is very nice!
Cons - like others have mentioned, it’s loud not only because of construction during the weekdays (noise will start around 6:30am), but it’s in a central location so it can be busy with passers-by and scooters until 1am on weekends. There seems to be zero noise muffling between the street and the apartment. If you’re cool with earplugs then this shouldn’t be a problem. Wifi signal was very weak and intermittent. When asked about this it took quite a while to get a reply (it was eventually looked into but there was no “fix”).
I’d add for other guests that you should just abandon trying to find free parking in Ortigia as it’s very difficult. Instead park just across the two tiny parallel bridges in downtown Siracusa. There’s lots of free parking there (just look for white painted lines) and it’s only an extra 1-3 minute walk (so 8 minutes vs 5 minutes) vs paying €10/day at Talete which isn’t monitored or has security anyway. We did this and had zero issues. Also, eat at NonnAnge, it was our favourite spot and is also across the tiny bridge from Ortigia in downtown Siracusa. Great breakfast and brunch!
