A lot of thanks to Francesca! She is very hospitable and ready to answer every question.
Special thanks for the list of local cafes, it was very helpful!
The location is perfect! We never use any public transport and explore Florence by foot.
The flat is cozy and has all you need (dishes, coffee maker, dryer etc.).
The bathroom is tiny but we were warned and it didn't make us any trouble.
So I advise this flat to all who want to visit Florence as a tourist.
