Her apartment is absolutely clean and hygiene to the level of 4-5 stars hotel. Every time I stay in airbnb, I am always freak out about the hygiene. And her apartment is definitely let me ease this worries. In addition, the apartment is close to the church and almost walking distance to everywhere. We didn't take any taxi or bus during our stay.
She also very welcomed us during we check in and recommend quite a lot of nice restaurants which r really good. She also let us have a late check out as we catching a late train. But you need to check with her whether she has any guest right away after your stay. She is very easy going and kind.
I will definitely choose this apartment next time if I visit Florence again.
Thanks again Barbara!
