If you are looking for good price in the central Florence than this apartment is in great location and price is fine. It is OK for solo traveler or a couple. It is really small but for a few nights not an issue.
Bathroom is great but with an odor. It is not a big deal since if you close the door it will stay in bathroom. It is not a matter of cleanliness, bathroom was really clean and working perfect but we noticed the same whiff while walking in backstreets of historic center. It simply is an ancient but wonderful place, there are compromises to be made. I am just mentioning it to make my description real.
It is A/C we had issues with. There was a huge box which was blowing a cold air. But there was a choice: or sleep in hot room or stay awake while that box is loudly working. Also we were notified to take our garbage into garbage container when leaving. We did not because we could not find it. Also we thought that since we pay cleaning fees and let our room clean it would be OK.
In short: it is a good inexpensive small place in perfect location. But A/C issue should be dealt with. Otherwise not complains.
