Location is 10mins from Oslo central station. The room is with open kitchen and the building also provides free self service Laundry.
If check-in after 9pm, there will be no reception. You will have to call the hotline to get your access code to your room. We arrived just before 9pm so we didn’t experience that. Otherwise, I would have to go through the trouble after a long travelling day to use Skype to call the hotline( provided I have internet).
