Lucia and Diego have a beautiful apartment! My wife and I stayed there for a week for our 1st anniversary and enjoyed the independence of coming and going as we pleased without bothering anyone. The apartment is about a 30-40min easy walk from Santa Maria Novella train station, which you can hop on a train and be anywhere in Italy within 2hrs.
There is an amazing bakery and restaurant right down the street from the apartment that have been family owned for over 50 years. The main sites in Florence (art museum, cathedrals, etc) are about an hour walk from the apartment.
It's a beautiful centrally located city that you can travel from without hauling your luggage around on trains/planes, crowds, and .. Just trust me.
Love AirBNB and Lucia and Diego's place is a wonderful place! Just like the pictures and very beautiful.
