First of all, if you travel alone, read this carefully:
After booking the apartment in Airbnb we got a description via WA: the apartment is located on a supermarket parking space with no other apartment buildings around. Seems like an old office building. This information was missing in the Airbnb description! We arrived and there was no key in the keybox, the main door was open - then on the way up someone just gave us the keys with no explanation. We didn't know who he was and what he was doing there first.
It's a building with two floors - one apartment and then above the Airbnb apartments. The front door which leads to the 5 apartments didn't have a lock, seemed like someone tried to break in and it wasn't repaired. This door was always open. The door to our room also didn't close correctly and seemed insecure. If I would've traveled alone as a women, I definitely would have felt unsafe! We wrote Edwar our concerns and in the next morning he came and "repaired" something at the room door, but we didn't notice a difference afterwards.
The walls are very very thin, the first night we weren't able to sleep until 3 o'clock because the neighbors were talking and listening to music. For this price it seems like a rip-off, if you find something else in Bologna, we wouldn't recommend the "apartment".
Also it wasn't really clean: the bin in the bathroom wasn't emptied, the bin in the room was just dumped, but the bag wasn't changed. Under both beds was a lot of dust and dirt. And beside the big bed at the wall it seemed it wasn't wiped for a long time.
