This is harrasment.
I strongly suggest moving to somewhere else, and if they ask why tell them you're being harrassed by the landlord's daughter..
Either that or stick your "the world's most irritating noises" cd on full and repeat, then "forget" to turn it off when you go out for a long weekend

There's a time when the operation of the machine becomes so odious—makes you so sick at heart—that you can't take part. You can't even passively take part.
And you've got to put your bodies upon the gears and upon the wheels, upon the levers, upon all the apparatus, and you've got to make it stop.
And you've got to indicate to the people who run it, to the people who own it, that unless you're free, the machine will be prevented from working at all."
