Gaia's place was fantastic. It is centrally located in Florence, and the apartment is quiet at night. The apartment itself is really beautiful with nice tile and brickwork throughout. The space is well utilized (dining table indoors and out, television, three bathrooms, full kitchen, etc), fully stocked (there were many serving dishes, cooking pots, bowls, espresso mugs, etc), and very clean. It is perfect for two couples -- both bedrooms have their own bathrooms and are on opposite sides of the apartment.
There are a lot of useful stores in the neighborhood. There is a grocery store and coffee shop just around the corner, and there are many restaurants. It takes about 15 minutes to walk to the apartment from the train station.
