In general a pretty good deal for a House in florence. The flat is very tiny, but for just a couple of nights it's doable. The price is very competitive, especially because it's really close to the center (around 10/15 mins to the Uffizi) however it's not the most comfortable flat.
The issue is that the photos do not show how small it is. The space inside the bathroom is quite claustrophobic. I'm around 1.85 cm and I could barely stand, which is ok but needs to be considered. The second issue is the top bunk bed. It's short, so you'll most probably sleep with your feet out and the ceiling is dangerously close to your head, with a long iron beam running in the middle. Finally the flat is very dark, with no natural light coming from outside and no windows so the ventilation relies on a small fan.
All in all it's a good stay if you are young and want to save money, but mind that it's a small room built to be an apartment, however it has all you could need, kitchen included
