I lived in Alangrange last year, its ok....
Most of the students are from China, so forget about good social life if you are not. They mostly stay in their rooms chatting on facebook/skype.
As for sharing showers/kitchens it depends on how lucky you are. The garbage was never taken out in my kitchen and some students dont know how to flush a toilet!
On the plus side, Alangrange is almost on campus and its all postgrads so it tends to be quiet and good for studying. Personally, I wish I lived in town in private accommodation, which is cheaper and better overall value.
