We spent 11 nights at Sabrina's flat in Via del Leone. The flat was nice and spacious for two, light, comfortable and clean with a well-equipped kitchen. The television and wifi came in handy. There were plenty of things to see in the local area, and a really friendly and well-stocked grocer's shop at the end of the road. Venturing over the river took about 15 minutes, with lots to see/eat en route.
Sabrina was extremely helpful when we arrived, showing us around the flat. She left some juice, pasta and wine as a welcome present. We didn't have any problems or particular questions during our stay, but would not have hesitated to contact her if necessary. I'd definitely consider staying here again on a return trip to Florence.
