I don't think most people have been to Kagrenzel, even if your picture is almost the same as the one at UESP.
The marker may not show until you're already part way up the obscure path that leads to it, so it probably doesn't get found unless a radiant quest selects it.

umm, wait, the hut in viridian woods? where you help the viridian sentinel?
That bed is commonly found in orc longhouses, the barked wood is suggestive of a primitive style. I now recall that I can also sometimes see it in the little round huts that our Exorcised Coven Cottage is based on.
