Absolutely perfect with one exception (no fan or AC).

Location: great spot right across the Arno River surrounded by great, non-touristic restaurants. Walking distance (~15 minutes) to all major sights.

Host: Incredibly friendly and hospitable. Carola opened up her home to us to where we (my wife and I) felt extremely comfortable and welcome.

Accommodations: The one room for rent is the guest bedroom of the apartment. The room was simple, yet well appointed. The style and furnishings of the entire apartment were very nice. The rooftop terrace was a beautiful place to enjoy a beer or glass of wine in the evening. As stated before, my only one complaint is the fact that there was no fan or air conditioning in our room. We happened to be in Florence during a heat wave and it was stifling hot in the room.

Overall, I give the rental 4 out of 5 stars. It would have been a perfect 5 if the room was cooler.
