Opened in 2014, the 25 Hours Bikini hotel has injected some much-needed "Ost-side" chic into the West Berlin hotel scene. Being situated right next to the city’s main zoo—which houses the most animals of all zoos in Germany—has given the hotel not only some interesting views, but also a neat conceptual theme for German designer Werner Aisslinger. The interior blends together a slew of funky furnishings—such as fur-lined hammocks, Vitra hanging chairs, and Moroso-esque sofas—with quirky touches like exposed concrete and bicycles stuck to the walls, and surrounds it all with an abundance of tropical plant life. Aisslinger’s playful approach informs the rooms, too, which are inventive and smart. They are split between "Jungle," which look over the zoo’s animal enclosures, and "Urban," which face out across Breitscheidplatz and the WWII-damaged Kaiser Wilhelm Memorial Church. The rooms are found along deliberately darkened corridors illuminated only by rows of glowing room numbers.
