Gianlucas place was the same as in the pictures - clean, cozy and the neighborhood is very nice and quite too. Its very good value for money! Definitely recommend.
Apartment is walkable distance from the main tourism objects. (10-15 min).
Also the owners are very, very nice and friendly. We had a little trouble finding a cab at central station (long story) but they were very patient and let as in the apartment later.
Even more - Gianlucas wife was very smiley and joking around.
We are definitely coming back to Bologna and definitely going to stay at this apartment.
One little tip - if you think you can find a taxi in Saturday evening at Bologna central station you are wrong :D there is at least 50 more people thinking the same.
