We arrived by train to Florence and walked to the apartment and were surprised that it actually was less than a 15 minute walk, with luggage. And, we are one block from the Duomo and around the corner was the Bargello and the uffizi. This has to be the best location in Florence.
The apartment is VERY quiet, beautiful, and has everything you would need to make your stay perfect. The a/c worked well in the 95 deg. heat, the showers were strong, and we had plenty of hot water. We had TV but never turned it on. There is a pastry/coffee shop right across the street where we went went for coffee every morning.
I have rented a lot of apartments via AirBnB, HomeAway, VRBO but this is the best located and best appointed in the last 20 yrs of my travels (I rented hotels before and I make about 5 trips/yr).
Silvia responded to our emails quickly and friendly, we were sorry we did not get to meet her. If you are coming to Florence, this is the only place to stay. There are five us us, myself, daughter, son-in-law, and two teenage boys and we all voted this the best.
