This is a great place to stay. It was clean and quiet, and felt safe to me, while being in the midst of the city and all the things you want to see. I walked everywhere and also could come back to the apartment midday to rest or regroup. I arrived to the train station, which is an easy walk even with bags and I departed to the airport with an easy walk to the tram.
It was helpful to have a fridge but I didn't stay long enough to do any cooking. It's pretty bare bones, no frills, but still has Florence charm and definitely worth the price.
