The other reviews are true: Marina is perhaps the nicest Airbnb host I have ever met. You can tell she cares very much about hosting and her place was a highlight of our first visit to Florence. Communication with her was super easy, she replies to messages quickly.
It's an easy walk from the train station and nearby attractions. It's also near Mercato Centrale and other restaurants that she suggested when she welcomed us on our arrival. Her dining recommendations were perfect and I suggest everybody try them out. The apartment is clean, quiet, and a perfect home for your Florence trip.
