Nico was great! He rented a car seat for my daughter so that he was able to pick us up and drop us off at the train station. We also did a tour with him to Pisa, and he went out of the way to drive over to the coast so we could have a look at the sea and have some lunch.
The apartment location was really great, walking distance in a few minutes to many markets, shopping and restaurants. I would definitely like to stay here again if we go back to Florence.
