The apartament is perfectly located. You can walk to all nice destinations in Firenze, and there are very fancy shops around and great restaurants.
Annoying situations were: complaint of our late arrival (we've waited for one hour in line for a taxi at train station), need of security amount, passport photos, need of apartment inspection earlier than check out time and very rigorous check out (Mathiew was there at 10:58hs). I am sure they could perform better ....
