San Lorenzo, Paraguay

This suburb of Asunción may be the third most populous city in Paraguay, but with a population of 225,395, it still feels like a crowded university town. The National University of Asunción campus dominates the landscape, making it a hub for education, though the hot, rainy climate and bureaucratic headaches are persistent challenges. While the economy revolves around trade and manufacturing, the city's main attractions seem to be its football team and composer Clementino Ocampos - hardly a ringing endorsement for those seeking an international, cosmopolitan lifestyle.
