Thank you for hosting us Laura and Donatella! Laura & Donatella are extremely helpful and gave us a lot of tips where to visit. Apartment was extremely clean and very close to the bus stop. you can use bus no 73 to reach the center it will take about 25 mins.
There is a tabaccheria near the apartment which sells delicious latte macchiato and croissants! you can also buy tickets for the bus from there!
Definitely will visit Milan again, it was a beautiful holiday!
