My partner and I stayed at Valentina's place for four nights.
The apartment is beautifully designed and has many historical features with a few new, more modern aesthetics. The stairs for example are really cool.
However the best feature of the apartment is its location right it the heart of Ortigia, which is one of the most beautiful towns I have ever visited.
We were a stones throw away from bars, shops, restaurants and only a short walk to the attractions in Siracusa.
All in all a fantastic apartment that is great value. Will be sure to stay again.
