I stood at Monicas house for 4 weeks. It was always clean and there was enough space for me to work and relax on the weekend. The location is very good connected to the center and to two supermarkets and the Bicocca Village where you can find some good restaurants if you don't want to go far away.
Monica seemed a bit annoyed when I tried to talk to her, but generally she explained me everything I needed to know and I only saw her a few times. She also offered me to use Netflix on her TV.
I totally recommend to stay at her house.
