Serena's sister was minutes away when we arrived. She was very friendly and went over the whole apartment and how things work. Showed us where to park and where to catch the tram to the duomo (steps away). It was a lovely apartment and looks just like the pictures. The only thing to know is that it was very hot when we were there and so we needed to open the windows for some air. It was very loud throughout the night. I am sure that with the windows closed it would be much quieter.
