It apparently goes for Nordic hotels in general. In fact, I had a couple of exchanges with the front desk a few weeks ago about the defective relay I'd diagnosed in our Helsinki room's wiring which periodically turned off all the room lights. Two days later, I realized there was a very poorly-placed, unlabeled master switch on each side of the headboard which was doing exactly what it was designed to do. The outer switch of each of these pairs controlled the reading lamp, but the inner switch -- the one you were really likely to hit with the pillow if, like Mrs. Goes, you like to place the pillow in a convenient orientation for sitting up in bed -- was the master switch which reset the room lights to the default.

I discovered pretty quickly that I could get the lights working again by removing the card from the slot by the door and reinserting it, but that also turned most of them on.

I can appreciate the value of a master switch to turn everything off, but it would be nice to label it and make it visually distinct from all the other switches in the room.
