The place is clean and modern. When we arrived, Daniele showed us our room and then offered to answer questions about Florence. He discussed lots of places of interest and circled the sites on a map (He probably spent at least 30 minutes with us). He was very welcoming and clearly likes meeting people.
We didn't get to meet Clara person (you may have read in other reviews that the AirBnB is with the family, but they live in a separate apartment now), but Clara was very responsive online and wrote back quickly when we needed info. about transportation and help finding local facilities.
I am sensitive to sound and I slept with earplugs, only because of a bit of car traffic you could hear. There were no noisy tourists in the streets below. This is a Florentine residential neighborhood.
It was convenient to be able to use the frig. and the shared kitchen space is conducive to meeting the other travelers, which gave it a nice atmosphere.
