I would highly recommend staying with Araceli. Both her and her husband were incredibly welcoming, and kind to me at all times. I was given an abundance of information on the area and Florence upon arrival. Including restaurant recommendations and local supermarkets etc, which I found very useful. They are so polite and sweet, and always made sure you were ok.
The apartment itself is lovely and authentically Italian. The room is incredibly spacious, clean and comfortable. It is within walking distance to the centre, yet you feel like you are experiencing a real Italian neighbourhood.
Overall, I would definitely recommend staying here. I had nothing but a positive experience and really enjoyed my time here.
