The description is accurate, the room and bathroom was nice and clean. Mario was such a friendly and helpful host. He helped us to find great value parking where we could leave the car off the street for 10euros. It took us 20 minutes to walk straight into the historic centre of Florence, which we didn't mind, Mario also let us know about all the local transport we could take, local shops etc.
His best recommendation was to try the indoor street food market on the first floor of the covered market in the centre, which we did (twice!) - it's got fantastic authentic choices at a good value prices. Don't miss it.
The only thing I'd say is that it does feel a bit like a hostel, not that this is a bad thing. But we were woken very early by neighbouring guests. The house rules do state that guests should maintain a considerate silence between 10 - 8 or somethings... but what can you do.
