This is one of the best Airbnbs I have visited. You're not in the immediate downtown, but Florence is small and the neighborhood itself is charming, calm, authentic and makes for pleasant morning strolls.
Luca is kind, responsive, helpful, the apartment is beautiful and the room is large and quiet. The price is incredibly good. I recommend this to anyone, the only exception being if you want to be in the immediate center, but that will cost you more and it will be a lot less peaceful.
