They're El Salvador (San Salvador) and Costa Rica (San Jose).
San Salvador, the capital of El Salvador, is the second largest city in Central America (after Guatemala City in Guatemala), home to an entire third of the El Salvador population.
As a result, San Salvador contains affluent suburbs as well as slums, representing the discrepancy in the country's distribution of wealth. Still recovering in many ways from an extended history of violence, San Salvador can be sprawling, grimy and chaotic. But once compromising first impressions are set aside, many travelers will discover San Salvador's other side: friendly, globe-conscious, cultured -- even sophisticated.
For more info, here's an overview of San Salvador from About.com.
Situated in the broad, fertile Valle Central 3,800 feet (1,160 metres) above sea level, it was called Villa Nueva when it was settled in 1736. San Jose developed slowly as a tobacco centre in the Spanish colonial era.
Downtown San Jose is the busiest part of town. A maze of streets and avenues, here you can find most of the city’s museums as well as a number of hotels and plazas.
