Bratislava M. R. Štefánik Airport

Official Languages: Slovak

English Is Widely Spoken in Bratislava, Košice, the Tatras and by Most People under Forty, and Hotel and Restaurant Staff Switch to It Unasked. It Thins Out in Villages, Where German Helps near the Austrian Border and Hungarian Is Everyday Speech across the South. Czech Is Understood Everywhere
