Was very pleased upon arrival that the apartment looked as illustrated in the pics (we have stayed in some apartments where pictures were deceiving). Very modern looking and kitchen was well stocked with essentials. Welcoming by host, Francesca, was average.
Looking back, this would not be a place I would choose to stay at again for three reasons:
1) cleanliness: floors were dirty as I could not walk around bare foot for without my feet turning black from the dirt;
2) air conditioning: apartment has air conditioning but host restricts changes in both temperature and strength of fan (set to low). I can fully respect shutting off power (lights and air conditioning) before leaving the apartment but what's the point of paying for a/c if you cannot modify the temperature to your comfort (I've never come across other air b&b's that have this same restriction by the host). Needless to say, temperature was auto-set too warm. With the a/c unit in a separate room from the bedroom, sleep temperature was too warm;
3) bed: good size (king) but mattress was much too flimsy due to the coil mattress. If your partner moves, you can feel every movement.
If you can live with all 3 of the above, this is a good choice. However, there are likely better suited apartments in the price point which are located in the heart of Florence (same side of the bridge as the train station).
