We had a nice stay at Edoardo's place. The location was perfect -- walkable to all the sights and many restaurants, but not in an overly busy part of town. The apartment is quite small, but it is laid out in a very functional way. We had a bit of trouble finding it because we did not realize that there are two types of street numbers in Florence, ones for businesses and ones for residences, but otherwise everything else went very smoothly!
