Instead of Elena we met her boyfriend who was very friendly and gave us many tips for our stay (Gelateria della Musica!!!). He even had some pasta and ingredients for us prepared.
The apartment is located in an old building, very nice and modern. The loft bed however, is kinda noisy. So is the bar next door on the weekend. So don't forget your Oropax ;-)
The house number is not the correct one, so don't worry if your GPS tells you to stop too early. In the neighbourhood you find everything you need and the best ice in Milan. With the tram or bus you get easily to Porta Genova or the other metro station.
Especially if you're by car, a great place to stay!
