We can highly recommend this wonderful apartment. It has great location with views of the river, the dome and Palzzo Vechio. It was well equipped with lovely extras and personal touches. Kay is a superhost and really deserves this. He helped us get rid of an old broken suitcase and had many very useful suggestions including recommending excellent restaurants.
The apartment was very clean, warm (it was quite cold outside at night) and comfortable. It also was quiet and we could have a relaxing time.
We certainly would return when we visit Florence again.
