The listing was as expected, with plenty of space and tastefully decorated. Be aware, though, that there is some street noise as the windows face the street. It is quite convenient, located close to the tram that leads to the Duomo and also next to a taxi stand. There is also a Carrefour around the corner, a pharmacy, and lots of restaurants nearby.
Cristiana was very responsive to my questions and requests throughout the stay, and I would definitely recommend to stay at her apartment during your time in Milan!
