David's apartment is really in an ideal location. Only 10 minutes walk (or less, but I have short legs :-) from all there is to see in Bologna. And the Mambo, with their grand Morandi collection, just around the corner! I also recommend to eat something in the little restaurant below 'Piano Gusto' (or Gusto Piano), the food is so nice, the wines are excellent. The apartment itself is also to be recommended, it is so clean and neat, with a nice little balcony.
