My girlfriend and I enjoyed our stay at Michele's place.
When we arrived, around 9:45pm, Michele was ready and waiting for us. He was very gracious and welcoming as a host. He gave us a map of Bologna as well as handy tips for first time visitors.
His place is nice, it is located on a slightly busy street. At night, it can get pretty loud but that's because it's a student city. The window does a sufficient job of cutting out the noise.
The apartment however is at the top of the stairs, which is quite a journey up but good exercise nonetheless. Being 6'3, the bed was a little short but still comfortable.
The shower is a little awkward but gets the job done.
Our only issue we experienced was that the washer was broken. It was written on the guide that it didn't work (but we didn't see) so we had put our clothes in and it locked them. Luckily, Michele was available and came up about 20 mins after our message to help us get our stuff.
I would recommend Michele's place to solo or duo travellers looking to explore Bologna.
