Was a really nice four days stay. We rented a car from Rome airport and drove to Firenze directly. Host were waiting and held a parking spot for us already. We got 3 adults and 2 kids. Enough beds for everyone and very comfortable. I like the equipped washer so we can do laundry for baby. Two bedrooms are facing street but still quiet enough at nights.
The apartment locates near highways and also bus stops. 10 min to a supermarket and lots of stores surround.
As a big group we used the rental car to go to Pisa and La pisza. You will find empty spots in the morning when ppl go out to work but if you come back late at night then it is hard to find a blue zone to park. Gonna need to circle around and also expand the radius of searching. Good thing is you could always walk back to the apartment without worrying even during late night. It was a very safe community I assume. One night I ended up just park on the side of a road that is illegal without issue as long as you come to move your car to a blue zone in the next morning. You could see others park at bus stop,sidewalk and even in the middle of the road, as long as you dont block the traffic. I think this is a general case for Firenze as a historical city.
