Regarding the Verhuurdersdeklaring, it's tricky / not possible for me to have this filled...

1. We're supposed to avoid contact with the landlord as a request from the main tenant because of various disagreements between her and us (moisture, lack of heating, etc).
2. I don't know who the landlord is and she doesn't know who I am neither (I'm not on the rental contract but can register through a declaration from the main tenant).

Else I've attached documents, let me know if that seems good.
