Dr Michael Willhardt, who runs a PR agency, is one of the few native Germans to remain in the district. "I've lived here all my life, and have always tried to keep the area in good shape, attract young professionals, and make it a pleasant place to be," he said. "We feel totally abandoned by the government, who do nothing to support these people and leave us in this state," he said. "If you invite in guests, you have to have someone at the welcome desk."
