Nicola's house is located in 20 minutes walk from the Center.
So, I recommend when other people go to Firenze center, take bus No.22 just near the house. It will bring you Duomo directly.
This house is not located inside the ZTL, we could park the car his private area distanced 3 minutes walk. The parking place is safe, but the gate is quite small. It was a big challenge to drive my Van into the gate.
The house door is ground floor just near the road. (But it was not noisy.) And bedroom and toilet is basement. Kitchen has enough facilities and laundry machine is useful.
For us (3 adults 3 children), two night was great.
However, the basement floor was little bit cold during the night.
