We stay in this flat for one night in Florence. It was functional but not the most comfortable flat we've airbnb'd.
Pros:
Centrally located
Check in was easy
Has all of the basics: kitchen, bathroom, bedroom
Bed was comfortable
Great price
Negatives:
You will be climbing 6 flights of stairs through a dark windy staircase to get to the flat.
Unless you are under 5 feet, you will be ducking in the bedroom.
The view of the duomo is out a tiny window to the side of the TV- so we never enjoyed it from the flat.
It was clean and worked for one night.
