First, couple of words before we skip to the obvious: Antonella was a great host, very kind, hospitable, responsive, responsible, polite and friendly.
In my experience, unless I needed something, I did not even notice there was somebody else in the apartment. I was also happy enough that Antonella had some spare time to show me around the town, provide information and introduce to some locations and details I would skip otherwise.
Now, the obvious part: that view from the balcony is AMAZING and photos provided on the Airbnb do not it justice. It offers unobstructed 360 panorama of Florence with all of its monuments (if you climb up Arnolfo Tower, or Campanile di Giotto, or dom of the Cathedral you would obviously miss those in the panorama) PLUS view over surrounding hills with towers, churches, villas and cypresses. I can only imagine how beautiful it is in late may.
