I'm still traveling so may expand upon this but Carla is truly a "super host". She was friendly and a great communicator. Her place was a welcome sanctuary/home base for a Florence experience.
The apt is located in the absolute heart of the tourist beast in the city center, steps away from the Duomo. But at the end of a day immersed in the museums, churches and crowds, it was great to be able to have a clean, quiet, well furnished home to return to.
Highest rating. Carla is the best.
