Andrea was a great host. Very friendly and easy to communicate with. He also gave us great tips as where to go and where to eat.
The apartment is located just next to Piazza Romana which is the entrance to the old city. We parked the car at the private parking of the building and walked to all Florence attractions.
The only problem we had is that there was only one portable a/c at the apartment. In the heat of July it was a significant disadvantage.
