Our favorite place in Italy!
My family, myself, and a friend (total 5) stayed at Marco's while making our way through Italy on a 10-day journey. We needed to check in early, and Marco graciously let us drop our bags at the apt hours before the scheduled check-in. We met his parents, who were still cleaning the apartment upon our arrival. They welcomed us warmly and gave us tips on where to eat and what to see in the city.
We loved everything about this AirBnB, but our main praises were cleanliness, thoughtful touches, and location. The apartment was spotless and felt thoroughly cleansed (vs. masked with industrial strength cleaners). The major attractions such as Duomo and Academia were within walking distance from Marco's, and the food and cafes near the apartment were less crowded and touristy than across the river (perfect for breakfast and dinner).
Highly recommend staying with Marco if you're in Firenze! He, his family, and this apartment are a real gem that will enhance your experience in this city.
