I enjoyed my stay at Luisa's place. She is a great host. My flight got delayed and I reached her place at 12 AM, but she was up so that I could be let in. She also helped me a lot with buying the right tickets for using public transport. I would definitely recommend her place for a stay in Milan. Just one thing to note, the doors don't lock. It's not a huge issue since the room and washroom are only for the guests. Also there is no fan in the room. Other than that, it's an amazing place to stay at.
