Valentina is a great host! Unfortunately we didn't spend a long time with her because she had to move from Milano (we slept in her room), but she was really friendly. We had a great time with his roommate Sergio who gave us some good addresses to go to, and he even proposed to share his meal with us!!
Metro by 5min walking. City center by 10min metro. Supermarket very close, and you can use the kitchen.
I recommend +++++
