Livia's place was amazing. Centralized in the town of Florence, a few minutes away from the train station and the Duomo. She provided great communication and instructions leading up to our arrival. When we did arrive, she provided some spots for lunch and dinner that were great.
At one point our wifi card she let us use had stopped working, but she was very accommodating and had it replaced immediately. The place is great and I recommend people to stay here. The only thing I suggest is bring earplugs if you are a light sleeper. The area can get very loud.
