Why stay anywhere else? This is the most convenient (5mins & €15.00 from the airport by taxi outside) and best ever value you can get in Bologna - clean & fresh room with bathroom, shower, aircon plus free WiFi.
Ok so it's basic, but with really friendly and uber helpful staff it's just refreshing. Must have the best value '&B' deal as well (I think €3-4 extra) available from 0700-1000hrs.
There's an out of hours area with coffee and snacks vending m/c you can sit at too, nothing flash just clean, new and easy.
If you want a bar and more expensive hotel facilities it's not for you, but for value, ease and friendly stop over it's an absolute no brainer. Also a car hire desk in the reception (targetrent.it).
Hotel is recently under new ownership and refurbishment, I I don't doubt it will be a roaring success. Good luck!
