Going to Kopenhagen, please help

Hi everyone,

I´m sorry if i can't speak or writte in danish, i know though you people in the nordic countries have a fluent english. :)

I obtained a very small scholarship for Germany and it's about to end, but i stay in Europe for a couple weeks more.This is the first time i visit Europe and for me it doesn't get better than winter to visit the continent.Well, i'm going to Kopenhagen this sunday 23th december from Berlin, and i would really appreciate if you could help me with some info.

- Where can i find very cheap hostels in Kopenhagen?
- Where can i eat for a reasonable price?
- What can i do around the city?
- What is the cheapest way to travel from Berlin to Kopenhagen?
- What else would you recommend me?

As you can see, i'm going on a budget, and i also know Denmark as a whole is one of the most expensive places in the world to live and to visit, but i would really like to be there at least once and see your land. i would stay for only 2 days.

Thank you very much in advance to all : )

BTW. i'm 29 and unfortunately can't enjoy the discount privileges of being under 25.
