Excellent location for a stay in Florence.
Every amenity for a long or short stay. I just spent a month at Barbara's place and was able to walk to just about everywhere in under a mile including the central train station. The bus stop is across the street(great transportation system) and 2 food markets within 2-3 blocks. Restaurants, cafes, bakeries and bars abound in the very safe neighborhood. As a single woman i had absolutely no problems walking around in the evenings. The rooftop offered beautiful views of the city and surrounding neighborhood while enjoying an espresso and croissant early or a glass of local wine later.
Barbara and her Dad were wonderful and communication was quick. I highly reccomend staying on this side of the river to experience the culture. And of course you must stay at Barbara's.
