Excellent location. This house corresponds fully to the way it is advertised.
One piece of advice: when going to Florence, if possible avoid having a car. If you are on a road trip, as we were, then there is an important principle: within the city you should use Google Maps to find Via Ricasoli, not Waze. There are two underground parking garages on Via Ricasoli which is convenient, but they are quite expensive: around 30€ per day, depending on the size of the car.
