Gorgeous apartment in a very convenient location. We were able to walk to all of the major spots in a matter of minutes. Federico was very informative and provided lots of great recommendations. He even had strawberries and wine waiting for us at check-in.
Only downside of the trip in Florence was the difficulty of getting taxis, download AppTaxi and find the taxi meeting locations on the map as they aren't good over the phone and can't be hailed.
Overall wonderful place and experience!
