Have you ever told the landlords what's going on when they always show up unannounced to check their house? Or is it under monument protection and they are waiting for it to become dilapidated?
They can stand there as long as they want, but if they haven't made an appointment with you beforehand, you don't have to let them in and you don't have to deal with them if you don't have time.
I wouldn't stay one minute longer than necessary in a moldy apartment.
The expensive kitchen can also be taken out and installed in a new apartment; if it just starts to develop mold, it is worthless.
>It is very stressful, the current situation, as I primarily do not want to expose the children to any dangers.
If you say there is already mold on the walls everywhere, then you are already doing that.
I would also recommend that you contact the tenant protection association and prepare to move.
