Nordic Countries - Inexpensive clean hotel near Oslo.

Does anyone know of a clean inexpensive hotel near Oslo for the night of the 10th of June 2009?

I can't find anything on Radisson, Hilton, ICHG, Marriott or Hyatt. Help?

Hmm, looks like there's a big maritime expo on. A quick search on Hotels.com found nothing in Oslo, Gardermoen, Lysaker, and only a $500+ room "within 25 miles of" Drammen (one hour away by train). You might try B&Bs and even simpler properties like Cochs Pensjonat (http://cochspensjonat.no/englishindex.html). Good luck!
