We really enjoyed staying at Martina's apartment and wish we could have stayed longer. It is in a fantastic, quiet, and safe location. Only a five minute walk from the train station and to the Mercato Centrale. Also within 10 minutes walking of lots of other key sites in Florence. Lots of very good restaurants near by. Apartment was very clean, nice kitchen (even though we didn't use it), comfortable bed, and a nice size bathroom. WiFi service was excellent as well.
Only minor issue, we thought the laundry would be in the apartment, but it is located within the apartment complex (short walk) and does cost extra to operate equipment. Again, minor issue but was unexpected since we needed to use laundry during our travels. Laundry detergent was provided by Martina, so we appreciated that.
We had a great time in Florence and definitely recommend staying here!
