We really enjoyed our stay in Florence and our stay at Nicola's apartment. It felt very safe and was very clean and comfortable. Shower was hot, bed was nice and comfy, and the AC worked well. It ended up being a bit more of a walk from the restaurants and sites we were trying to visit than we thought, but thats okay. We just got plenty of exercise! Otherwise it is pretty easy to access the train station and metros to the airport etc. We recommend!
