I had 5 days in Bologna staying at Francesco's place, and I enjoyed everything.
First of, I got delayed on my way to Italy, but Francesco stayed up waiting for me to arrive anyway - that's a good host!
During my days there he was super attentive and wanted to make sure that everything was good.
If you have any questions he's more than happy to help you out.
I was so lucky to be in Bologna one of the days that he was doing a play at a small theater and he kindly invited me to go.
If you're looking for a good place in Bologna, with a kind host, close to the city center - then this is your place :)
I would gladly stay with Francesco again.
