Hi Budeen,
The
top attractions to visit in Warsaw's Old Town are: the Castle Square, where you can watch street entertainers and dancers. And, the Royal Castle, which was the home for many czars during the World War I.
In
Warsaw's New Town, the must-see attractions are: the Sapieha Palace, St. Kazimierz Church and the Royal Route.
Hope this helps
