The room turns out to be the best choice we made in our stay in Italy. It's located in a historical site in the heart of Florence, minutes walk to all the places of interests like Uffizi in Florence. We never need to take bus during our stay, and can even walk back for a nap in the middle of visiting.
And the apartment is exactly like the images shown in the airbnb. The loft apartment is clean with washing machine, nice kitchen and a big TV. Very comfortable for the stay of a family.
Though sometimes there can be some noise from the street, but it seems inevitable for all the places we stayed in Italy, so should not be a disadvantage specific to this apartment. Also the host has been extremely friendly and even prepared some drinks and food for us.
I definitely recommend stay in this apartment if you would like to enjoy the historical atmosphere while also enjoy the modern convenience! Hope one day can revisit here!
