We stopped at Alessandro's place for just one night. Nevertheless, he was a super-host and we felt at home like long-standing friends. He was very welcoming and available to answer and accommodate our requests. He gave us good advice on what to visit in Bologna and where to eat. He also left the breakfast prepared for us, since we had to leave early in the morning.
The place is exactly as described, a shared apartment with your own private double room. A plus for the sauna that unfortunately we didn't use. Thanks Alessandro!
