Beautiful apartment in a convenient location -- you can't go wrong. The host was also extremely communicative and helpful. She provides guidebooks to Bologna in a bunch of languages in the apartment.
One thing to know about getting there -- if you tell a cab to go to Via Altaseta 2 or Via Altaseta 3, that works just as well as trying to explain the "2/3." The actual address number sign on the door says "3 2" but with a normal-sized 3 and a small 2.
