Claudia's apartment is in a great location. It is less than a 10 minute walk from the main train station. Claudia gave us excellent directions to her apartment. There is a market next door from her apartment where you can buy fresh food from Tuscany. We were greeted by Mr. Daniel who gave us wonderful recommendations on where to go and how to get there. He also told us about some wonderful local restaurants.
You can walk to a lot of the things to see in Florence from Claudia's apartment, so the location is fantastic in every way.
