It's been a little over a decade since I lived there, and yes, it was not all that crazy.

As a foreigner I was generally expected to stay away from big protests when they flared up, and internet connectivity sucked (though this was also a time when the world was less dependent on near-constant internet access). Otherwise it was pretty much like any other "middle-tier" country.

I was a teenager back then, so it was especially nice in certain ways: Tehran was pretty safe, so I had a lot of freedom to get around unsupervised that I later did not have in some other "more free" places.
