My friend and I stayed at Maurizio's place for 4 nights and it was a really great turn out. I know that most reviews that are reliable are those who give 3-4 stars but I honestly thought that this place HAD to be given 5.
It was our first time in Florence and he was so nice to inform us of where to go and what to do in the city from the moment we stepped through the door. Though we did have a language barrier we managed to get along and hold some conversations, with of course the help of google translate haha
He takes great pride in the roots of Italy and of his household and so it is completely understandable of the certain rules he has set out while you stay - nothing too hard it's just those simple keep tidy and respect those around you rules.
If I was ever to come to Italy again and visit Florence, this airbnb point would be on my list! It's a definite recommendation and so worth its price :)
