"The Harry Potter Lego sets are all fun and easy to build, but the Great hall is by far the most easily recognizable as the Harry Potter Hogwarts image you see in all of the movies and books.
Although the price seems intimidating at first, once I spent the money and assembled the set, I realized it was worth all the money I spent. By far my favorite part about the Harry Potter Lego sets is their unique ability to attach and complete the full Hogwarts castle.
I would recommended to anyone purchasing the full Hogwarts set and even the other Harry Potter Lego sets. From an adult perspective I can successfully finish the sets quite easily, but I have been an avid Lego builder for a while now, and find most of the newer Lego sets very easy.
I did not experience any particular challenges in this set, but found that it is mostly a set meant to be displayed rather than played with."
