We stayed in a very nice albergue in Najera. We had a private room but everyone got a bed with sheets and towels. This cabinet was on one side of the room. I don’t think we have ever had add much shelf space in a hotel room.
You can never have too many flat surfaces to put things on.
Xerox PARC did a study on how people organized their offices and found that most people used a system of piles. So they invented a “pile cabinet” basically like the cabinet in our room.
