Host Giovanni was super helpful. He answered promptly all my texts and emails, he was waiting for us at the door when we arrived, and he also carried my large suitcase up to the 3rd floor.
The apartment is as promised. It was spacious for our family (2 adults + 2 kids). The location is unbeatable - it is right next to the famous Uffizi gallery and close to Palazzo Vecchio. you can walk to all main attractions in Florence from this place. lots to shops and restaurants around.
Only downside is that the apartment is on the 3rd floor (note that in Europe, ground is floor 0).
