Norwegian student looking for accommondation in London

My name is Trine Andersen, and I'm a 21 years old girl from Norway. I'm moving to London in January to study at UCL and I'm majoring in Political Science. I', going on exchange with the erasmus program. I'm a very outgoing person and I'm used to living in dorms and shearing. Now I am studying for the semester in the US, so I will be travelling straight from here to London. I love having people around so student housing would be perfect, even though I prefer my own room. I would like to life central in London so I can be close to the university, and so I can experience as much as possible without that much travelling back an forth for my semester in London.
