Federico was fantastic to deal with and the check-in and check-out process was easy. The location was incredible, and the views amazing. However, the only 'warning' is the noise levels from the piazza below. At night you will hear music of buskers players (stopped at 9pmish each night), and early in the morning (5/6am) we were woken by the bell of the Duomo. The location and view trumped these comments about the noise.
