25 year old Brazilian guy, looking for accomodation from June 22nd to August 3rd

I'm looking for any type of accommodation, anywhere in Oslo during this summer. I'll be attending University of Oslo summer school, and need to find a [cheap] place to stay from June 22nd and August 3rd.

I'm doing masters in civil engineering in Brazil and will take a course at the UiO this summer. I do not smoke, I love pets and I love to make new friends. I'm also a quiet and adaptable person, but I love to engage in conversation while sharing a cup o coffee.

If you have any suggestions, please contact me. I'll be glad to talk to you.
