I contacted Valerio and Manual last minute, after I found myself waiting in front of another B&B door for more than an hour without reply. Valerio replied immediately and in less than 20 minutes everything was ready for my arrival.
I stayed at their place during 4 nights and it was a real pleasure! Valerio and Manuel are really welcoming and helpful, they gave me hints and tips about Bologna, maps, good restaurants, places to visits, what to do, etc. I definitely recommend to stay at their place.
The room is small yet very comfy, literally on the main place of Bologna, everything is at walking distance, the street is quiet and close to what ever you will need in Bologna. Nevertheless, they have a great coffee machine!
Thanks again Valerio and Manuel!
