Giulia's place was really good. It was 30 min walking from the train and 30 min walking to the Duomo (20 something if you walk fast). Which actually worked great to stay away from the noise. You do not have to walk, you can take a bus anywhere. Which the train station is close to her place.
She is a great host and very relaxed and easy going. She let us use her washing machine and dry our clothes in the balcony ( which you can see part of the dome of the Duomo).
I recommend the space, because you actually stay with the host, talk with her, see how they live in a way, which is what Airbnb is about in my opinion. It is not run like a hostal with self check in, rigid rules, and not interaction with the host. And She is a great host at that.
