We spent four nights at Lucio's apartment. It had everything that we needed from fully equipped kitchen where we cooked most of the evenings to comfortable furniture. In terms of location we could not ask for more: all distances were walkable, even to the central train station (30 min). Communication with Lucio and Margherita was flawless: they answered within 10- 15 minutes to my emails.
Overall, I could not wish for more during my little get away in Bologna.
