Stefano's apartment is one of the best values you will find. It was upscale, sparkling clean, and only about a 5 minute walk to the Duomo and Accademy Gallery (David). There was a bottle of wine waiting for us and we were able to walk everywhere. The only reason I can think why he doesn't charge more for his wonderful apartment is because it is a 20 minute walk from the train station which can seem longer when you're with your luggage. If you can manage that, this is the place to stay in Florence.
