Oslo hotels can be found throughout the city center, but note that they can be very expensive by U.S. standards; if you choose to stay in this area, be prepared to fork over the kroner. If you're looking for hotel discounts, try booking in July and August, when the city residents typically head for vacation. If you're traveling around Europe, Oslo is a great weekend getaway, and weekend travelers are rewarded with cheaper hotel rates.

Some Oslo hotels lack private bathrooms, so check with the management before booking to make sure your room will have all the amenities you expect (though you can save money by sharing a bathroom). 

• Oslo has the range of hotels you would expect of a capital city, as well as B&Bs, a smattering of guesthouses (pensjonater) and a quartet of youthhostels. To appreciate the full flavour of the city, you're best off staying on or near the western reaches of Karl Johans gate -- between the Stortinget and the Nationaltheatret -- though the well-heeled area to the north and west of the Royal Palace (Det Kongelige Slott) is enjoyable too." -- Rough Guides
• If the suburbs are more appealing to you, most accommodation there is also less expensive. An exception is Linne Hotel 7km from the city center." -- Travel Channel
