This was at an albergue where we stopped for coffee. 9 euros for a bed, 3 more for sheets, I would definitely take that. 4 euros for the short wash cycle, 5 for the long cycle, 2 each to use the kitchen.
We talked to a volunteer there who was German and there were two more Germans who worked there. We stayed at another place that was run by a German so maybe it is a German thing. I like the idea myself, you can get exactly what you want.
Note the complex wifi password. Almost in hexadecimal but not quite.
