If you’re looking for a place to stay in Bologna, and you don’t want a 20 minute walk to city center, I highly recommend Aemilia Hotel. The staff spoke excellent English, the room was modern and clean, and compared to a lot of hotels closer to the city square of similar quality the price was really excellent. During our stay in September 2011 we payed 62 euros per night, and when we called last minute to add another night onto our reservation I believe they charged us something like 90 euros.
I loved the branding of their bathroom products, and the glass-walled shower. They also had a garden area on the rooftop, and I think there was a hot tub as well, but we didn’t visit those. We did have to walk through some more deserted streets late at night to get back, but we never felt threatened or unsafe. It had free wi-fi with a password that you request from the front desk.
The breakfast provided was the second best we had in Italy. It had a large variety, and everything they set out was really well done. My favorite combinations were celery/brie/walnuts, and a spoonful of granola with yogurt and Nutella plopped on top.
