The apartment is great, very very spacious (much more than it looks in the pictures), recently renovated and refurbished, with all the amenities that you'd need even for a longer stay. We stayed 1 week working remotely, as such we spent most of the day at home and found it very comfortable. The apartment is outside the historical city center of Ortigia albeit it is only a 15-minute walk to get there, as such the apartment is great as a longer-term base for visiting Ortigia as well as take your car and visit the surroundings of Siracusa (our street had free parking anywhere, which is something you can't find in Ortigia, so it was great for a longer stay where you'd want to have your car at hand in front of the house but at the same time not shell out a fortune on touristy parking).
I wouldn't recommend the apartment for very short stays, as then you'd be better off spending the night in Ortigia right away, as that's where you'll go at night and for visiting. If you're only staying for a short visit and you don't mind a smaller space for the same price (the accommodations in Ortigia are typically quite cramped), then you won't need to come all the way out here for your stay. The building where the apartment is located is old and run-down, and there was almost always garbage in front of the building (mostly because the daily public service of garbage pick-up was not working properly). The immediate surroundings are also not nice.
If, however, you want to stay in a comfortable apartment for a longer time where you might also need to do some work (i.e. have reliable wifi, which we did), do laundry, cook (there is a fully furnished kitchen), watch TV (the apartment has a huge smart TV with Netflix, Prime, and the likes), etc, then this apartment is the right fit for you, and Giuseppe (the co-host) has been extremely responsive and present, going as far as to leave us a bunch of water bottles that lasted us the week basically, as well as wine bottles and the basics for cooking a meal when we arrived and hadn't had a chance yet to go grocery shopping.
