I stayed in Laura and Roberto's place for 4 days- they were there when I arrived to show me the place, and answer any questions. Checkin/Checkout was very smooth. The location is fantastic- I loved this area. It is a 5 minute walk to the local train station so you have easy access to/from the airport. The street has several local small restaurants, grocery stores, pharmacy, local shops - all within a 1-2 block walk. It's also only a 5-10 minute walk to Sempione Park, which leads to the Peace Arch and Sforzescso Castle. It's about a 20-25 minute walk to the other main tourist attractions.
The unit is in a building that is set back from the street and behind a building which faces the street, so noise from the street is very low. The unit is smaller, but very well laid out with all amenities needed for short and longer term stays. The pictures are accurate - the bed was very comfortable, and the internet was solid. I will return to Milan and definitely look to stay in this unit again.
