Lory's apartment is very nice to stay at! It is a little far from the city center compared to what airbnb shows, but it's not that bad, and there's quite a lot of busses from there, going most of the day, and it's close to a bigger supermarket.
The place is very clean, and if you haven't planned a lot for your stay there's quite a few recommendations there as well. Lory is also very nice and doesn't mind answering questions about Bologna.
