I have been visiting Florence for 11 years and this apartment was my favorite by far. It is clean, spacious and a great floor plan - open kitchen, dining and living, as well as spacious bedroom and bathroom.
The hosts pay attention to every detail, including a bottle of wine for their guests, capsules for the coffee machine, and other amenities for the kitchen, even laundry detergent if you need to clean some clothes.
I would highly recommend this apartment, it is in the Otrarno neighborhood, just steps from the Ponte Vecchio and Palazzo Pitti, and in a fairly quiet, cozy neighborhood
