We had 3 wonderful days in Valentina's apartment in the center of Ortigia. It is a very quiet location yet only a couple of steps to a very lively street leading up to the Duomo. The apartment is very spacious and has everything one needs for a comfortable stay. Since we were on an extended vacation, we really appreciated the convenience of a washing machine.
The beds were very comfortable. Since the buildings in Ortigia are super close together, there is not a lot of natural light in the apartment. One of the bedrooms has only tiny windows and a very low ceiling. Also noteworthy might be the many steps up to the apartment especially for people with heavy luggage.
There is parking available in the public lot called Taleta. It is a 10 minute walk from the apartment. Upon leaving, one of us stayed with the luggage nearby while the other one fetched the car.
Be aware that the keys to the front door and the apartment door are a little "temperamental". After a few attempts we got the hang of it.
The communication with Valentina was exceptional, she answered all our questions without delay. On the first day we asked for an umbrella for the upstairs patio and it was delivered within a couple of hours. Very nice!
We really enjoyed our stay!
