If you're looking for a place to stay in Florence, I couldn't recommend a better spot than Luciano & Tammara's apartment. It's in a perfect location — just across the river, meaning you can easily access the main tourist attractions (the Dome, the Uffizi, etc) in a five-to-ten minute walk across the Ponte Vecchio, but you get to enjoy a more low-key neighborhood of locals (and other people staying in Air BnBs, lol).
In the apartment itself, it's quite spacious and incredibly quiet and private. The pictures they have in the listing accurately capture how lovely the design is. I will say it's a tiny bit dark/drafty at times, so if the forecast calls for rain/chill while you're staying there, you likely won't be able to open the windows much and will appreciate the automated heating and the supplied duvet. They also offered wifi, which was incredibly useful as the data/roaming in the city is a bit slow if you're used to US speeds.
Luciano & Tammara were very responsive, offered lots of good advice, and have a booklet of suggestions for local spots in the area. (I will also say they happen to live just a few minutes walk from one of the best restaurants we visited while in Italy, Il Magazzino.) If you have the chance to stay at their place, you should!
