Perfect place to visit Firenze, the appartement is very nice and well situated.
You can almost visit everything by feet.
Depends on the days you may hear some noise on the street but normal as it’s in the center of the city.
Only attention point I would share is on the parking if your car is too big you may not succeed to enter due to the street which is tight. I have a Mercedes Class E, we tried 20 min without success, I had to put the car on a parking and paid 110€ for 3 days.
All the rest is just perfect, on my opinion difficult to find better in Firenze.
