Alessandra's place is a cute stylish flat in the wider center of Florence. I would come back on my next stay. Alessandra was a lovely host, she has a nice energy and a special touch for little details in her appartment.
There is a good restaurant run by Sicilian family just next door. The Sunday brunch at the Four Season Hotel, which is just around the corner, is spectacular.
Happy place for the stay in Firenze.
