My sister and I had a great stay at Roberto's and Marco's apartment. The apartment is charming and well decorated. I would say, one of my best experiences staying at an Airbnb. The neighborhood is full of character (the underground tunnel to city center is filled with amazing graffiti art work), and is only a pleasant 20 minute walk to the Duomo. We highly recommend this place and would plan on staying with them if/when we return to Florence.
