The apartment is great - clean, very spacious and it has very large windows so there is a lot of natural light, check in process is very smooth and the host is very responsive.
It is located close to all points of interest in Florence, it is just a few steps away from Via dei calzaiuoli - the main pedestrian street that connects piazza della Signoria with piazza Duomo. Also, it is located close to the Florence train station, we didn't even take a taxi to it, it took 10 minutes to get there on foot. There is a great gelateria across the street and a lot of great restaurants in the area. The only thing that you can be concerned about is street loudness in the evening, however, the host provides earplugs which is very helpful.
