We really enjoyed our stay at Guglielmo's place. Guglielmo came by after we let ourselves in and gave us plenty of information about the apartment and city. He also provided us with a cell phone which we used as a GPS. This was so incredibly useful during our stay. I would only recommend to make sure you confirm the self check in instructions in advance. We were a bit unclear on the instructions, but Guglielmo quickly responded and helped us figure it out.
