Romania's administration is relatively centralised and administrative subdivisions are therefore fairly simplified.
Most visits to Romania are trouble-free but you should be aware of the global risk of indiscriminate international terrorist attacks, which could be against civilian targets, including places frequented by foreigners.
Romania's currency is the "leu" (plural "lei") (it means "lion" in Romanian). It is the descendant of a Dutch currency that was used in this area in the 17th century.
