The apartment is very beautiful, clean, and spacious, with high ceilings and nice furniture. It stays cool even on hot days, and there is also A/C if you get hot. It is on the main street to go to Ortigia, which is a short walk away.
Désirée was very nice, and when we couldn't find soap in the apartment, she immediately came by and helped. She has been a really good host.
Parking can be difficult on the street, but you should be able to find something - otherwise you can park in the nearby lot.
I recommend this place, it is a great way to really enjoy Siracusa!
