I am considering visiting Prague in January or February. I have heard it is beautiful in winter but also very cold. Is it worth going in the off-season? What are the advantages and disadvantages compared to summer? I have heard the Christmas markets are good but those are in December. What is there to do in January? And how cold does it actually get? I am from a warm country and I am not sure how I will handle the cold. Any honest advice would help me decide.
