I had a long stay at Serena's place during my master's course. I would recommend it to any students for long-term stay at Marangoni or Politecnico. It is situated in a very safe and convenient, complete with security camera and keepers from morning until 2pm. The apartment is close to two large supermarket, one is 24hours. Tram stop right in front that will take you straight to Centrale or Garibaldi, and walkable from M1 Porta Venezia that will take you to Duomo in less than 10 mins. The area is close to shopping street Corso Buenos Aires filled with high street brands and a cool select shop called M Collection. Also close to Bar Basso, a famous place known as birthplace of negroni sbagliato.
The apartment is large and clean, kitchen well equipped with pots and pans, even with microwave/oven, large bed with great storage space. The bathroom is also large and clean. Serena is a kind and wonderful host that would help me deal with all sorts of things because I do not speak Italian. There are several books in the apartment that's very interesting too. I had the most wonderful time in this home and would always choose to come back here whenever I visit Milan again.
