I encountered a slight confusion over the apartment number but was quickly resolved after contacting Simonetta over Whatsapp. Simonetta personally met us at the apartment and gave us a walk through of her spacious and extremely clean apartment, and shared her recommendations on restaurants, supermarkets, gelato shop etc.
The apartment was very spacious for 2 persons, and within walking to all the tourist sites in Florence... all within 20min or less walk from the apartment.
We had a very comfortable stay.
