We did not get to know Gianni, but his parents, who live upstairs, were available and helpful. Communication was good and they let us leave our bags at the flat on our last day. Consider taking the bus back from Ragusa Ibla as it is quite a walk uphill.
The flat is fully equipped and functional (although the additional bed might not be suitable for a very tall person), the wifi works well and we even got biscuits and coffee for breakfast, which was a much appreaciated attention. Thank you!
