Okay, the tower itself is more the impressive, but the area around it is most definitely not. Construction everywhere, closed roads and highly annoying dust getting into clothes and shoes does not make for a great experience. In fact, I looked like a refugee with chalky, dust covered feet and shoes after visiting the Eiffel tower.
I'd personally suggest observing the Eiffel tower from one of the many Seine river cruises. The views are just as good and as an added bonus, you won't look like you emerged from an UN Relief camp.
