We had a nice time in Andrea's apartment!
The apartment has a bit of the cave atmosphere (in a good way) with beautiful atone wall and wooden doors. It's clean, comfortable and well equiped.
The kitchen is large and fit for cooking.

Andrea was very nice, came to pick us up and gave us tips regarding free parking and good cheap food in the area. He lives upstairs so there are no availability problems.
The location of the apartment is also a big plus, very convenient.
The area is very quiet at night, during the day you are left to the grace of the neighbors, who might want to listen to loud music or speak outside your door (the apartment is on the ground floor).
Also, the wi fi works only in some parts of the apartment.

All in all though I would recommend this apartment for a stay in the lovely Siracusa!
