Chiara's place is amazing.
Its big (3 person easily), clean, quiet and beautiful.
The communication with her was Always amazing.
We didnt heard any gate opening on the 3 nights we stayed there.
Its 15-20 mins foot away from everything you wanna see in florence.
About the wi-fi, it had a little problem with his charger, once we figured it out (It uses a cell phone charger), there were no problem at all.
Its a 5/5, for sure!
