This was by far our favorite Airbnb during our trip to Italy. The space is so lovely, the view is amazing, the location is perfect & so central. Also, the bed & pillows were unbelievably comfortable. The terrace is so wonderful and though it was cooler weather during our stay we loved sitting there to read or drink our coffee. Yes, there are plenty of stairs to get up to the apartment--but if you don't like stairs, you probably shouldn't be in Italy. ;) Plus, this place is 100% worth the climb.
When we arrived, Federico met us at the apartment and gave us all the details we could need, including some great books if you want to learn about the history and areas in Florence! He is very kind and hospitable, and it was immediately apparent how much time and care he puts into his Airbnb space and taking care of his guests.
Being so close to the Duomo, you will definitely hear the bells in the morning--but I assume most everyone in Florence gets to hear them too. We will definitely stay here again when we return!
