We stayed in Allesandra's apartment for 10 days and it was awesome. But let me start with a few drawbacks. It was quite noisy during the night (windows and balcony are facing the street and many scooters were driving by. We normally live in a very quiet neighbourhood so the noise was waking us up sometimes). The kitchen was quite small, but we knew about it from the photos and all in all we had no problems with preparing meals.
Now the good stuff. Alessandra is a charmingly nice person. We arrived quite late at night and she bought us food and drinks for breakfast, including tipical Sicilian sweets and wine. She treated us with great care and responded to our every message almost instantly. When we needed something she would help us right away. Also she provided us with a notebook and a map of Ortigia full of tips and advice where to go and what to do (also outside Siracusa).
The apartment was super clean and newly renovated, everything was fresh and shiny. It is located about 15-20 minutes walking distance from Ortigia.
To sum up, we recommend Allesandra and her place to everyone. It was a perfect choice for our stay regarding price, quality of the apartment and most importantly Allesandra, who is a great person.
