CityLife is one of the newest areas in Milan. It features 3 unique skyscrapers, as well as a mall, a park and residential buildings. The area is mostly completed nowadays, even though there are still some buildings under construction.
It's very different from other places in Milan and Italy overall. Not a touristy place, but one that is nice for a walk. There are also many restaurants, and it's a great area for some shopping as well.
