Sleeping in the gutter takes on a whole new meaning at the Dasparkhotel. Constructed from repurposed concrete drain pipes, each individual tomb room offers a bed, storage, and power, while bathrooms and showers are shared among guests and are located nearby. A small window in the ceiling allows light in, a door code that's provided lets you in, and when you're done, you only pay what you want. Maybe the "gutter" isn't so bad after all.
