Caterina’s flat is very centrally located. From the bedroom window you can see into the Piazza Maggiore; opening the window the noise of the hustle and bustle of the street below hits you, and then with the window shut, you are back into the quiet space of a classic Bolognian property.
Caterina is very helpful, on hand when needed, but not intrusive. We were free to come and go and made ourselves completely at home. Although Caterina had friends round (it was a holiday weekend in Italy) we felt we had the place to ourselves. Our room was spacious, had a comfy bed, and was next to the shared bathroom. Check in and out (and bag storage) no problem.
I would thoroughly recommend Caterina’s place as a base to explore Bologna.
