We had a fantastic 2 night stay in Leonardo's apartment. Very close to the train station and to the main attractions of Florence. Shops right outside the front door, however very quiet in the unit. It is nicely decorated with everything that is needed for a short or long stay. Plenty of information about the area and even a map which came in handy. The balcony is great and we enjoyed our breakfast out there every morning!
It was very hot when we were there and Leonardo provided us with a portable air conditioner which was great!
Leonardo was a lovely host. He helped to carry the suitcases up and down the stairs and was very understanding when we were late upon arrival due to train delays.
The only thing to note is that there is no wifi in the apartment, but considering everything else this is definitely not a reason to overlook this place. I would recommend this unit to anyone visiting Florence.
