The previous tenant did not have something like that, I am in contact with her.

That wouldn't have only started when you moved. Ask the other neighbors.

Actually(!) it shouldn't smell if there is water standing in the siphon. The siphon can actually(?) only run dry if either very very little water comes from your side (it simply dries out then). We can probably rule that out, since you do wash dishes and so on. Or if on the wastewater side, occasionally or constantly, a vacuum develops that sucks the water out of your siphon.

Ideas:
- Let hot water run, then check by touching if your siphon contains water.
- Let hot(?) water run regularly and observe the smell (for example, be at home on Sunday and let water run every hour for 1 minute so that the siphon is filled).
- Try to figure out by careful watching and listening whether the siphon is being sucked empty.

Questions:
- Are there any leaks in the wastewater pipe after the siphon? The photo suggests an adventurous construction, is everything tight there? Any slip fitting with play?
- What kind of angle valve is that there?

Alternative procedure:
- Report the defect to the landlord ("smell"), request remediation, set a deadline, and if the defect persists after the deadline, reduce the rent appropriately. (Don’t waste the money, who knows...).

I once poured half a liter of vinegar and salt each into both drains overnight. After that, the stench was gone for 2 days. However, it came back....

Possibly the distance from the trap to the drain is a bit too long and the slope is not sufficient, causing unpleasant odors to form here.

Maybe the following installation can help. Of course, it’s also possible that I’m talking complete nonsense, but the experts will let me know ;)

Try Clorix, but please be careful with it. Make sure to rinse the vinegar away and pay attention to your clothing. Also pour Clorix into the overflow drains. Let it sit and then the drain will be completely clean. I would bet that afterwards nothing will smell anymore.
