Our time in Barbara's apartment was amazing! The apartment is located perfectly at Ponte Vecchio, you can easily walk everywhere from there but it's still quiet. Also Barbara was flexible with the Check-In and Check-Out times and always responded very fast and helpful. My bag was stolen the first evening in the city (watch out for your bag at Piazza del Duomo :D) with the key to the apartment in it. Barbara responded right away, send us her address and gave us a second key, so that we could enter the apartment at night. We would highly recommend it and always come back!
