We had a wonderful stay at Anna's apartment, it's easily 5 stars. Anna is hospitable, she helped us find a way to Chianti for wine tasting, made sure we had everything we needed, and furnished the apartment with everything you'll need for a short or long stay. You have views from 4 different directions around the apartment, the best being in the master bedroom looking over the Duomo and gorgeous Florentine rooftops.
The apartment is located directly in the center making it easy to walk to any of the nearby attractions Florence has to offer.
You should stay here.
