Room smells like marijuana or hashish

I'm afraid we won't get this out.

I’m afraid we won’t get this out here.

I don’t know where to look anymore either. Should first try to take a closer look at the plants in front of the window.

There is no mattress in the room

What is this bed on the photo covered with?

I already suggested that in ##12, 21.

What is this bed lined with in the photo?

It’s slowly turning into a hidden object picture here

So I also always had a strange smell sporadically in two rooms, at some point after I hadn't mopped for a week and then did, I noticed that the smell was there afterwards and generally always after mopping for 1-2 days. I then cleaned the floor with a steam cleaner and special cleaner, afterwards it was gone... maybe the same with you?

But I have also heard that older prefab houses sometimes develop a smell inside, maybe that's starting in that room now?
