I saw this place about 4 years ago with some friends. I definitely reccomend that you visit it, historically, culturally and in terms of its architecture it is definitely a place worth seeing. Expect to share the place with a lot of people though, it gets really busy, starts to feel like a tourist trap. The best thing is when you get out of the forbidden city you can walk up this little hill that overlooks it, on a clear day it’s a fantastic view not only of the forbidden city but also of Beijing.
