What can be said about the BLQ Pratello..
The location is perfect ! The apartment is absolutely great. Clean, stylish, comfortable as your own home and with all amnesties needed (great Wi-Fi by the way). I'd recommend to make the best of Via del pratello, which has a lot of great places to eat and drink.
And for closure, Giovanni is a great host and was very helpful throughout our stay.
All and all, the best place to be in Bologna.
