There were 5 of us here for 3 nights and we were very comfortable at Marco’s. The apartment was very clean. The location was very convenient for walking to the Duomo and Gallerie dell'Accademia. There were many great restaurants nearby. There is only one AC unit, which is near the front of the apartment so the bedrooms did get warm, but there were fans in each bedroom. We would definitely recommend staying here while in Florence!
