My stay was pretty good overall. There are a few things worth noting. First is that the building is quite old (like many in Florence) and there's a fairly strong musty odor in the hallway on the ground floor. It's 98% gone inside the apartment, but if you're sensitive to smell or must/bacteria it's worth knowing. When I ran the AC upstairs, it would dredge up a little bit of this air (or it's in the filter) but that seemed temporary.
The wifi was also very inconsistent. I frequently lost connection on my phone only to discover I was using cell data. It held up for my Zoom meetings, however. This is likely standard in Florence.
The unit is very dark - good for sleeping but not ideal while I was working remotely from the living room. Narrow streets don't allow for big exposure. I only bring it up because the pictures make the unit look quite bright, but that is a long exposure photography technique. The interior lighting consists of several bare bulbs, high up just above eye line. I find this lighting style to be irritating. Maybe I'm nitpicking but it can make/break a room's comfortability in my experience.
