Kameha Grand

The wing-shaped building alone stops traffic on the Rhine, and that's before Marcel Wanders finishes his work inside. This design hotel in Bonn reads like a Dalí painting with a geothermal power plant in the basement, a very German detail the surrealist aesthetic somehow makes charming. Themed suites run from "game room" to "ladies suite" with extremely flattering lighting. The rooftop infinity pool dissolves into the river, and the spa's glass-walled sauna overlooks Bonn.
