This is one of the nicest Airbnbs we have stayed at. The room is very spacious and has a nice charm! :) It also has everything you need, including basic kitchen utensils and a nice little area with chairs and a couch to relax. The room was also very clean and we slept perfectly thanks to the comfortable bed + pillows and the AC.
The check-in was also quite smooth and the host later sent us a long list with nice recommendations on where to eat and what to do in Florence!
While the room is not located directly in the center it is very well connected by the tram which runs regularly and reaches the center in 10min. (There is also a bus which we did not use though).
All in all a great experience and would definitely stay here again when in Florence!! :)
