My wife and I stayed at Donatella’s for 3 nights with our 10-month old child, and we really felt home. The flat is beautiful, with a lot of light and a gorgeous terrace, which we enjoyed very much. The location is also great, right in the centre of the old city and walking distance to via Etna, Teatro Bellini, piazza del Duomo. Also, right in the middle of Catania’s movida but still quiet at night.
We didn't have the chance to meet Donatella but her father was available all the time and had been very helpful. I’d definitely go back.
