Had to pay 60 kr extra for linens, bed sheets and towel, was not informed of that ahead of time. Mandatory payment, otherwise we wouldn't get access. When we arrived there was no pillow covers or towels provided.
Met another person in the hallway who told me he didn't get any linens or sheets at all, despite paying for it ahead of time.
Sleeping can be difficult if you don't have earplugs, there's constant noise from the street, and people in the room would go in and out of the room a lot late at night.
Pro was the self-check-in. You got pin codes for the doors so you could just go in on your own, very convenient.
