We stayed in Maria's apartment in December, and even though this was out of season there were many things to do and see. The apartment was outstanding in many ways, beautifully appointed with every thing you would need, stylish and very clean.
The location was excellent as it is close to The Duomo, sea and many excellent restaurants.
Maria was an excellent hosts giving very helpful advice. If you are visiting Ortigia this would be an outstanding place to stay.
