Today, I have an open view into the sewage pipe that comes down from the upper floor, not a pleasant sight I know - but now it's finally going to be enclosed (after over 2 years in the house) 
The pipe goes down in a space next to the stairs that is about 30x70cm, cold and hot water are also routed in the same place.
Now that it's going to be enclosed, I want to minimize as much flushing and running noise as possible.
I'm thinking of filling the space with mineral wool and then putting double drywall on the 3 sides I can access.
Am I on the right track, or should I consider other solutions?

A baseboard in stone wool usually works well for this. They are 5cm thick.
Otherwise, there are sound-dampening drainage pipes, e.g., Poloplast, which fit directly onto standard PVC parts.

I had the same in my hallway. It made a hell of a noise. I think the sound has disappeared enough just after enclosing the pipe with sawdust+plasterboard. An inspection hatch can be good, the reason we had the pipe open was that a previous owner had experienced the pipe starting to leak and therefore wanted to keep an eye on it.
I filled with what I had at hand, it turned out to be fiberglass. I pressed in as much as I could and applied single-layer drywall. It turned out quite okay. Flushing upstairs can still be heard if it's quiet in the house and you're standing nearby. If you have double-layer drywall, I think it will be very good.
Bitumen sheet around the pipe, available self-adhesive at e.g. mekonomen. Dampens due to its weight and makes it very effective.
It is used, among other things, to prevent the sheet metal in the car from yielding when you have some stereo, can also be used for general soundproofing.
