Christina was a great host, and the place we stayed in was just like king's palace. The apartment was super neat, clean and cosy. It took us about 7 minutes to reach Duomo (on foot, of course). And, btw, you can find a big food market not far from the apartment (15 min), where you can find everything to cook a perfect meal at your kitchen. I definitely recommend this place to stay in during your Florence trip!
