We stayed at Mariella and Milko's for a week at the height of summer and it was just perfect for us. It's a lovely size and it's nice and cool with a beautiful little patio outside and, best of all, it's right next to all the great sights of Ortygia. The flat was incredibly lovely and clean and Mariella and Milko were the loveliest host and had some outstanding recommendations for local spots. Couldn't recommend this place higher.
