I stayed with my elderly parents at Donatas flat. We had a great time in Bologna (it's totally worth a visit) and we were very content with the flat (my parents are used to hotels but they were really enthusiastic about it). I was especially happy about the two bathrooms (what a luxury!), the flat ist practically organized, the kitchen is very well equipped and even though it's a rooftop apartment there is a lot of light. I also enjoyed the balcony. We definitely recommend Donata's flat.
Donata is a very friendly and helpful host, she organized a taxi for us and communication was really easy. Thanks for the beer and the snack!
