Stefano has been very good at communicating and was very prompt with our check in. His place was so central. We got the Firenze card during our stay and all attractions were within walking distance of his place. The apartment was close enough where you could stop in 2 or 3 times a day to take a break from all the museums. Due to the location being so central you may notice that some nights might get a bit noisy from the streets. This can be improved by completely closing the shutters and windows.
Overall excellent stay!
