Everything was great except 3 things.
1- breakfast: old fruit, old ham & cheese, basic cakes... not horrible, but definitely not worth a 4 star hotel.
2- Our room faced a nice terrace on the roof, which came as a surprise; the main french door opened on it, and so did the toilet's window. there were 2 sun beds, a round table and 2 chairs. But... we soon discovered that the terrace was not ours, but shared with all guests, via another access door. That meant anyone could watch us through the french door or the toilet window, unless we kept blinds closed, and the room dark, always using lamps. We never saw sun light in the room, it was very poor.
3- noisy fridge, also leaking ice/water inside.
friendly staff, ideal position to visit Ortigia daily without having to park in Ortigia which is nearly impossible), easy access to local beaches, and to further ones towards South too. Good wi-fi signal, clean sheets every 2 days.
