This apartment is great... very much like the photos. It's quite large for Europe, and the photos reflect the actual size (vs hotel listings that use lenses that make rooms look bigger).
The location is super convenient for visiting the main attractions in Florence, buying groceries, warm breakfast croissants at Gino's, and (of course) tons of restaurants. It's on a pedestrian-only alley, which reduces the street noise. (Florence is busier than I expected, though activity drops suddenly between ~10p-11p.)
During my somewhat long stay, I had one plumbing issue come up and it was handled promptly.
