We didn't see Alessandra, the apartment is managed by an agency.
The apartment is fine for short break - maybe for a few days. It's on one of the the busiest main streets, so parking isn't easy to find.
Good points were: The location; the bathroom, shower etc. and the comfortable double mattress. The small kitchen and sofa area will suffice if you are planning to eat out; however, the kitchen utensils etc. are minimal, so cooking a main meal isn't easily achievable. If you are arriving at night, after the shops close, make sure you take a bottle of drinking water and a toilet roll...as these weren't provided.
It's a good choice for a maximum of 2 people who eat out and want to be within walking distance of amenities and local tourist sites including Ortigia.
