Couch-surfing in Iran: Any questions?

Stephan Orth, a 35-year-old German writer and editor, went to Iran for two months last year. While there he got arrested (and released two hours later). He got fake-married (and released 10 days later). He couch-surfed in the homes of a dominatrix and a black-market winemaker, among others. And he came back convinced that Iranians are the most hospitable people he has ever visited.
