I enjoyed staying in Vincenzo's flat! The pictures were accurate, the apartment is walking distance from the train station, and walking distance from Florence's historic center.
I arrived at night and met with Vincenzo's roommate, Eleonora, who very kindly let me in and explained everything about the apartment. I got to meet Vincenzo the next morning. He was very nice and suggested a few places around town to eat, provided me with a map and directions. Unfortunately we didn't spend much more time hanging out because I was mostly out in town hitting all the main attractions Florence has to offer. I would absolutely come back to this apartment, and recommend it was well.
