The location is very good, close to restaurants, monuments and the train station. There is a coffee shop in front of the building and a supermarket one block away. Florence is a very busy city so you may want to book a table at the restaurant of your choice to ensure you can have dinner as you planned.
The place is big as described, however from the 4 rooms it has, only 2 have A.C. what wasn't convenient for us, for example we were not able to sit at the dinning/living room because it was too hot to stay there.
In order to keep the place cool, we had to close all the blinds, so there was not natural light in the place.
There are 2 small bathrooms with shower. If you are a tall person the size of the shower may be an inconvenient for you.
The washer works perfectly.
The is a terrace but you are not allowed to go out since there are signs indicating not to step out to the terrace.
Finally, when you check in you are asked to show your IDs for security purposes but you are also asked to sign some paperwork with the details of the Airbnb rental wha twasn't specified in the listing.
Our mayor issue was that the place was not fully supported by A.C.but we managed and enjoyed Florence.
