This is a great place to stay! It is very clean and safe. The train is only a short walk away and with one stop to the centre of Florence, you can't ask for more.
It is removed enough that you can get quiet from the hustle of Florence and close enough for you to jump back in within minutes. Lorenzo was very gracious in staying for us to check-in as we got stuck in traffic for a diplomat that was coming through the city. Also, he sat with us to walk through the apartment and also helped us find local restaurants, grocery stores and educated us on the train system
We would recommend this as a great stay for anyone...oh yes, the trains. You will hear them as you are near the train line. However, they quickly vanish as you fall asleep. It is a very small thing to endure while being close the the heart of Florence...again, this is a great place to stay!
