Gianluca was very welcoming and helpful, even when we locked ourselves out (make sure you take both sets of keys out with you!). The flat has large bedrooms and is well equipped. As others have pointed out it can be noisy especially if you are not used to living in the centre of a bustling lively place - but the location more than made up for it - it was good to stand on the balcony and watch the people passing below. Also his recommendation for a restaurant, Dioniso, was excellent. We loved Ortigia, ancient, beautiful, buzzy and serene.
