Great location but since Florence is so small, it's hard to find a place that isn't with 20 minutes walking distance of everything else. As for the apt, it was a decent place but probably needs some renovations or updating. Three of us stayed in this place during a very hot summer and it feels as if the place isn't meant to accommodate people during that season. The A/C downstairs worked fine, the A/C in the main bedroom upstairs barely felt cold and the 2nd "bedroom" was more of a small room with two non-functional fans in them so our 3rd preferred sleeping on the sofa downstairs.
I thought Sid was very nice, showed us our place and tried to help us book a reservation to a restaurant which I appreciated but I thought the check-in process was archaic with him having to manually give us the key/let us in within a 3 hour window. Also felt obliged to tell us about every breaker in the house which makes me assume that the A/C and electricity is a known issue. I asked him about the upstairs shower not draining well and the broken fans and he said he would come the next day to fix them but never came, I think he may have been feeling a little sick at the time (but this made me enjoy the manual tour even less).
Overall probably a great place normally when the weather is nicer and if you get a decent price but I don't think I would return in the summer again.
