I had a very nice stay at Francesco's. He communicated the location and how to get there very nicely both from the center and from the airport, and was a very friendly and nice host. The place was cozy and clean and I actually was happily surprised about the room regarding the size. If you want a very central location or stay out very late, Francesco's house may not be the best option for you as it takes a little while to go there from the center. However, the place is actually very close to the tram stop, in a peaceful and quiet neighborhood so if you don't mind not being at the center of the action, I would very warmly recommend staying with Francesco.
