We absolutely loved our stay. The apartment is located slightly away from the center in a neighborhood with local families. It is extremely safe and we felt relaxed walking around. The apartment was so lovely and beautifully decorated. We had everything we needed to cook, the shower had great water pressure and temperature, and the bed was so comfy.
The apartment is about two blocks from the river Arno which is great if you happen to stay over New Years and would like to view fireworks. It is within 10 min walking distance of any of the main sights in Florence and a 15 min walk from the main train station.
Francesca was such a lovely host and so responsive. She helped us with every question we had and also provided local recommendations. I highly recommend exploring the area around the apartment if you stay because the restaurants offer more local cuisine.
This is the place I would stay if I come to Firenze again!
