This place is amazing! There were 6 of us staying there and I was a little worried based on the photos that it would be a bit too small for us, but there was no need to be concerned! The apartment was perfectly sized, with well-functioning air-conditioning and wifi. The shared balcony is great, with opportunity to socialise with incidental neighbours, and a view of the two towers (Asinelli and Garisenda). The beds are surprisingly comfortable too! The only possible downside is that the shower is a bit small, but that was an almost insignificant concern considering how good everything else was.
It is likely you won't find a better location in Bologna either. It's right around the corner from the university and restaurants and towers and churches and bars, but still quiet enough to be able to sleep well. I would absolutely stay here again, for all future visits to the city.
