The hub of Warsaw is the Rynek Starego Miasta, the market square in the young Old Town. This is where vacationers and Warsaw residents meet to party, store and go out. For sightseeing, head to the Royal Castle and to concerts in the alternative Praga. Hotels in the Polish capital of Warsaw are at home in a charming and impulsive city. Next to Warsaw's castles, Stalinist-style skyscrapers meet modern monuments.
