Silvia is awesome. She waited us until past the check-in time since our train was late and got delayed. She had a map for us and gave us some tips on were to eat and things to do.
She also let us keep our bag after check-out, which was very helpful considering all the things we wanted to do on that last day in Florence.
The room is located close to the principal things you might want to visit in Florence, and just a few blocks from the train station.
