I strongly recommend Oriella's flat to ones who want to visit Milano for a couple of days.
It is quite near (5 minutes on food) to the Navigli region and to the subway station Porta Genova. Porta Genova is on the M2 metroline, and you can easily arrive to the Central Station or Lampugnano (Flixbus Station) or to the city center, il Duomo, Sforza Castle etc... by using subway. You can also walk to the city center: It takes about 20-25 minutes to the Duomo, and the road is quite fascinating.
By the way, Navigli is my favorite destination in Milano. In this safe and lively neighborhood, you can find several restaurants, pubs, bars, and anything you need.
The flat was much better than I expected. It was very well designed, clean and comfortable. I was alone, but three people (one couple + one single) can also stay there without being in trouble.
If I can visit Milano once more, I would like to stay in this flat again.
