I think the new concept that you have to pay cash for your sheets, linen, is kind of stupid. The clerks said it was because you could bring your own and save you some money. It kind of misses the point, a bed should always have sheets in a hotel, nobody goes travelling around whith a lot sheet to sleep in every hotel they are staying, next step maybe it is having to pay for you bed or bringing your own in addition to the stay price which is not so low as having to pay extra for sheets, even most hostels include linen. There are not "do not disturb" signs in the room which you can hung on the door so that room service do not disturb you if you are sleeping or doing something private (like being in the bathroom). They just knocked once and came in. I had to ask them to close the door, which they did twice, but did not lock it. So those small details put down the whole experience, I was so angry with being disturbe two days in a row that I decided to check out one day before, they did not even care, just say, ok then will check you out, bye bye. I am paying for a service, and I want it to be good, not having the feeling that I am getting it for free. :(
It was the cheapest single room in Oslo at booking time, however Kr. 800 for a small room with no sheets included is kind of expensive anyways. There were cheaper places but not so central or with shared room. So no possible privacy.
