Nicoletta did an amazing job welcoming us to Florence and introducing us to the area. She had a map ready for us and pointed out all of the hot spots and all of her favorite places. she answered all of our questions very thoroughly and was a pleasure to talk to. Her apartment is beautiful and very clean. The neighborhood seemed a little sketchy at first, especially since there was construction on the neighboring street, but after walking around both during the day and at night, we felt very comfortable. It is a ~15-20min walk to the Duomo... Definitely manageable. Cost about 12 euro for a cab ride, which Nicoletta provided us the number for. We had a great stay in Florence thanks to Nicoletta's hospitality and guidance. Grazie mille!!!
