Iconic, long-lasting, and serving as the official hotel for the Berlinale, the Hotel Zoo is as established as they come. Recently given a facelift by the American design-team Dayna Lee and Ted Berner, it has now emerged as an imaginative update that still honors its glorious past. With its sly in-house speakeasy-themed bar, impressive dining room offering three meals a day, and attentive service, it's a good option for those wanting luxury but tired of the traditional approaches.
