This apartment was really lovely and perfectly located.
The apartment is walking distance to the train station and a few minute walk to the Duomo. Alain was beyond helpful and super responsive by email. When we arrived, he took the time to map out all of the attractions in Florence along with his favorite eateries and nearby supermarkets.
We stayed at the beginning of July and it was unbearably hot in Florence, but you would never know it in the apartment because the air conditioning upstairs worked like a dream. The apartment is as shown in the pictures and the view from the courtyard of the Duomo really can't be beat.
We would highly recommend this apartment.
