The room Stefano offered was exactly as spacious, clean and nice as described as well as the rest of his private apartment.
Very shortly after I had booked the room on Airbnb Stefano sent me a detailed description on how to get to his place from the main station in Florence. Also it was easy to find a time I could move my luggage in and get the keys. Stefano explained how the air condition works and other details of his apartment.
I felt very welcome.
