The Stadtturm is a quick and easy attraction, worth doing when in Innsbruck if only to orient yourselves and to take a very good pictures of Innsbruck and the surrounding area.
Be warned, there are quite a number of stairs to climb and no elevator, but it is not too onerous, and if you have a Fitbit, it will help your stair count considerably!
My wife, two daughters (8 and 10), handled the stairs without a problem. When we arrived at the top, we found very nice views of the city and met a number of nice people willing to take pictures of us.
It is a bit cramped up at the top, so people need to be friendly and patient with one another. The entire visit does not take very long, so it is a nice thing to do just to get one's bearing on the town and its surroundings.
Definitely worth doing.
