Casuzza is a tiny, cozy place in the heart of Ortigia: you will have all the historical sites of Siracusa just out of your door, plus restaurants pubs and more. It can fit a couple, or even a single person as in my case; the little house is modern, clean, and fully furnished.
Last, but not least, Patrizia is a lovely host, she took care of everything during my stay.
Honestly I couldn't find a better one
