It is, literally, a concrete jungle - but prefers to describe itself as a city of gardens and parks.
It doesn't matter which side of the political spectrum you profess to hold, whether you are leftist or right-wing, you will ALWAYS receive the ire of its citizens if you criticise Vienna for being an inhuman, desperate city. And yet, in many ways, it really is a desperate place, full of yearning and misery. You only have to take a walk down one of the many, many gasse (roads) where only a bare ribbon of sky is exposed, and hear for yourself the lamentations of its citizens. The Viennese are not friendly, and never will be, as theirs is the culture of duplicity refined. But of course, tourists looking for Beethoven and Mozart won't notice, because Vienna is very good at distracting the visitor from its ugly core.
It is not a friendly place, either - well except maybe for a few weeks in early Spring, as things thaw out and the winters piles of dogshit melt.. I've lived here for 12 years, and type this from a villa looking out over Turkenschanzpark, which is one of the places considered so valuable to the citizens who believe it is the greenest city in the world. Its true, once you're in the park, its easy to forget the hell that surrounds it.
Of course, if I'd been born here, I wouldn't see all of this in such a dark light. But as I was born in a state where the wide open sky is not a privilege but rather a right, I find the Viennese love of their prison quaint and irregular.
