The city of Boccaccio and of Machiavelli is certainly not a place to visit for only a night, but for me, this night was an essential stopover, and Mariantonietta's home was easy to find after a short walk from the station. She greeted me warmly, and was most gracious in her hospitality, offering exclusive use of a bedroom and a shower room, as well as access to a large kitchen area. The apartment is both comfortable and stylish, the kitchen well equipped, and the facilities in excellent order. The room is at the rear of the house, overlooking a quieter road (I think). I was awoken by early morning road sweeping, but this was a brief disturbance and it didn't trouble me. The bed was comfortable, and had I been too cold, there was extra bedding available. I didn't need it.
Communication was not optimal, but this was the fault of a recent upgrade by Airbnb (not compatible with my software), and nothing to do with Mariantonietta.
Though I had too little time to appreciate the wider city, I found the neighbourhood to be well-situated for a visit, close to the quiet streets surrounding the US Consulate, and to views of the Arno.
Florence should seem welcoming to any David, and thanks to Mariantonietta, this David felt at home.
