Hotel lets you sleep as if you are homeless

At first, I thought this could not be true. But this is a real hotel in Sweden that is trying to raise awareness for people that are really homeless. For $14 a night, you can sleep in what looks like a run down park bench - I guess to mimic what sleeping on the street may be like. I assume the experience would be unpleasant, motivating the sleeper to donate to homelessness charities.
