My mother and I recently stayed at Concetta's place on our first visit to Sicily and it was a breathtaking location.
On arrival, there is only 4-5 steps to get your luggage up to the lift access to the property. The lift then takes you to the rooftop terrace where your apartment is. The view from there is just absolutely stunning! We spent many morning, afternoon and evenings sitting outside watching both Ortigia and Syracuse! You don't need to wrestle the crowds to get a seat by the boat harbour to experience the sunset, you get an unprecedented one from your own balcony.
The unit itself is small but has everything you need (plus the deck gives you so much extra space). Perfect for a couple. The bathroom is spacious and the kitchen well equipped. Very private and easy to get to and from cafe's, shops, local morning markets and only 1km walk to the local swimming beaches. There is limited wifi so if you find you need to do a lot of things, may be better to utilise cafe's and restaurants data. Overall Concetta's place was wonderful and I think we have convinced many family and friends to stay there to experience Ortigia.
