I give a five stars notation to this appartment : wery well located, so clean and with a beautiful decoration. The flat is realy big to have a nice stay in Florence.
Alberto was very reactive for any kind of information and let us feel at home in his appartment.
Just an advise : bring some earplugs if you don't want to hear the bell of the Duomo in the morning . The price to pay for this so special location.
Thanks for all !
