My husband is a native of Prague (Praha). It's quite beautiful there around Christmas because they generally have snow that adds to the romantic look and feel of the place. They also have some different traditions. I have been to Prague many times, but with the exception of my wedding visit in May, 20+ years ago, Christmas was the loveliest time. I had the benefit of spending it with hubby's family. I hope you get to go some day. I'd be happy to provide recommendations for things to see.
