We were in Bologna for just two days and booked last-minute, we were very lucky that due to a cancellation on short notice the apartment was free. It was very clean and provided everything we needed. The communication was swift and friendly and check-in and out was very easy thanks to the key-box outside. There are two doublebeds on two floors, but no doors. For us it didnt matter, but good to be aware of when travelling with groups.
I would definitely come again, nonetheless. :)
