Concierge.com's insider take:
A design hotel in a period 19th-century patrician building, the Bleibtreu (which means "stay true") was Berlin's pioneer boutique property when it opened in 1995 just steps from the Kurfürstendamm. The place has a Birkenstock heart; the 60 stylish rooms, as well as the common spaces, are decorated with environmentally friendly untreated woods and all-natural textiles, which infuse the property with a sense of Gemütlichkeit (coziness). Yet the aesthetic manages to feel Manolo Blahnik sleek, with custom-made modern furniture and bold color schemes of blue, red, and yellowcomplemented by the sculptures and paintings of Berlin-based artists. The reception area is unobtrusively tucked away off a tree-shaded courtyarda swell spot for an alfresco drink. There's also a florist shop, a restaurant that's earned accolades for its healthy menu, and a serene one-treatment-room spa.
