Check in was very straight forward.
Location is very convenient: it is a 1 minute walk from the Paolo Uchello tram station. It is about a 5 minute tram ride from the central station.
The room is clean and the bed comfortable. The bathroom may or may not be private, I'm not sure, but we never had any issues with it being occupied. To get to the bathroom you do have to walk through shared space.
Mauricio is a very kind-hearted and wonderful host. He does not speak English, but is willing to put some effort in to communication to make sure you are comfortable.
We would recommend this air bnb for anyone visiting Florence who is willing to use the public transit.
