Mimmo is a very nice host, he was very flexible as we arrived very late in the evening. Also, the communication was very smooth with him, he always replied in minutes. The location of the flat is perfect, couple of mins by foot from the Duomo. The room and bathroom were very clean, well equipped. Mimmo and his wife were always very helpful and they suggested us very nice restaurants, places to go. I highly recommend them, best choice if you go to Florence :)
