Gaia's place in Florence was perfect for us. Easily accommodated my wife and our two teenagers (14 and 18). Only about a 5 minute walk to the train station and similar walk to most of the central meeting points for tours, as well as Duomo and other sites. Check-in was easy and Gaia provides a great list of suggested spots near the apartment (grocery, restaurants, etc.). I would highly recommend this to anyone visiting Florence.
