Concierge.com's insider take:
This sinuous navy-blue five-story block is the work of architects Romero and Schaefle, but it's the contribution of landscape designer Günther Vogt that looms largest: All 18 rooms face into the interior courtyard garden. This is half-Zen, half-Brothers Grimm, with its fairy groves of slim-trunked silver birches and its reflecting pools with floating flower heads. Inside the bedrooms, a rounded pillar contrasts with a cubic block of closets; a frosted-glass bathroom wall with a sun-flooded skylight; all in shades of white. There's a wooden-walled cigar bar, readings (in German) and other cultural events, and a Slow Food restaurantall in keeping with the intellectually socially progressive ideas of the hotel's namesake, Swiss labor movement pioneer Herman Greulich. Unsurprisingly, its neighborhood, Aussersihl, is trendy.
