21 year old Kiwi Girl looking for accommodation in Utrecht!

I am an exchange student from New Zealand and will be starting my studies at Utrecht University in September. I am desperate for a place to live! I would like to find somewhere close to the city centre, or to uni. I would like to find a sociable flat with similar aged people who will be keen to go for meals or drinks together every now and then or hang out in the lounge to chat and watch movies, not always locked away in their rooms. Dutch or international! Gender unimportant. I am friendly girl, always up to try new things and meet new people :)
