I have stayed at Moxy Bergen and there is something resembling a very small desk but it is far from ideal. Also not a chair with back support, but a stool, so not good for any longer work sessions for me at least. Also no closet, you get a couple of hangers and you are meant to hang your stuff on the metal grid on the wall.
Hotel is pretty basic but OK for a couple of nights in my opinion, nice location and breakfast was fine too.
You can see the "desk" in room here:
