Gianluca and Elena are lovely, lovely hosts. The apartment is literally down the street from Due Torri, one of the best known sights of Bologna. It's close to all other worthy of seeing sights, for that matter. The street the apartment is in is one of the liveliest it seemed - as my friend (who studies in the city) said, it's full of (mainly) freshman students hanging out. For those worried about noise: you can't hear any of it as the apartment faces away from the street so that's a major plus. Totally recommend this place!
