I stayed at Giulia's apartment for 2 months and overall it was decent. The location was very close to the Gioia metro station (M2/Green line) and it felt very safe walking home at night on my own from the station. Also, it was quite close to Centrale too, so it was easy to catch a train to other cities or to catch the bus to the airport.
I didn't get to interact much with the family because I was working long hours everyday and by the time I got home, we were all doing our own things, but they were nice whenever we talked. Babar, the wolf-dog is also very sweet after he calms down but he needs time to get used to you.
The room was nice and spacious, but just beware of the low hanging chandelier because I've bumped my head several times on it... but it is pretty to look at! Also, the bed is quite hard but I didn't have an issue with it. The bathroom was usually clean, but I thought that toilet paper would be provided. Instead, I had to buy it myself (cheap but inconvenient to carry)
