Barbara was very responsive and patient with us when we were dealing with a nightmare of a trip to Florence (trains were cancelled, immense delays, stressful bus rides), allowing us to arrive and begin to relax again.
Her apartment is perfectly located just across the Ponte Vecchio, leading to quick and easy access to the Otrarno bars/restaurants, the sights across the river, or a half-dozen fantastic gelato shops within a couple of blocks.
She had some of the best amenities we found during our stay (easily best shower, darkest room at night, and a toaster oven)! if you're looking to stay in Florence we would highly recommend Barbara!
