21 year old girl, looking for either one room or a whole apartment in Copenhagen

Hi there, myself and my two friends (1 girl and 1 boy) are looking for accomodation in Copenhagen. We will be doing an internship with the World Health Organisation from April 10 until the end of June (12 weeks approx.). Ideally, we would all live together 2 bedrooms would do, or 1 bedroom with 2 single beds and a pull out couch. 

However we are also looking out for single rooms if we do not manage to find an entire apartment.
