Giulio's place is right behind the Duomo, which has a wonderful view as you can see in his picture, but you will still be amazed when you realy see it. We only had one night in Florence so we stayed at Giulio's place for a very short time, which was a huge regret for us! The location is nice, clean, near by the train station and Giulio is really easy to communicate and solved our questions promptly.
Definitely would recommend this apartment to anyone travels to Florence.
