The place was amazing, just like photos, very modern. Bed & pillows are very comfortable. The kitchen has everything it needs for the most part. The view from the balcony is serene. There is a store nearby (Conad), about 3-4 min away & lots of restaurants to eat at, including gluten free pizza right around the corner. The location is great if you want to see the major sights in Florence.
However, the floor is very cold. If you are staying during the colder months (I stayed in February) definitely bring slippers or wear your shoes (even after exiting the shower). Warm socks don't help, I've tried. There is also a hotel right above and the walls/ceiling is very thin. You will hear everything (literally, everything).
My overall experience was good. There was a problem with the temperature in the flat, but Stephanie was quick to respond & help out with that.
