My girlfriend and I stayed three nights in Lorenzo's apartment and were very happy with it. It is perfectely located in the very centre of Firence, only a short walk to Palazzo Vecchio and the Duomo.
The interior and atmosphere is simply amazing. It is a charming old house and living there almost feels like taking part in Florence's history. The flat was also clean and equipped with everything we needed.
Loronze is a kind host, thanks to his instruction Check-in and Check-out were smooth. He answered fast and was always available.
I highly recommend the apartment to everyone who would like to visit Florence!
