The landlord should've thrown in a heads up about this neighbor. But alas, it could've been worse. Could've been like that one landlord who admitted to being a criminally dumb criminal, to a tenant.
Anyways, in this case, the rent seeming like it was too good to be true, was in fact, too good to be true. You see, there was no disclosure that the apartment being rented would also be shared with a loudmouthed, rude, obnoxiously toxic, neighbor. The kind that fills the air with negative chaos, and generally infects their surroundings with unease. Fortunately, a pro revenge was hatched, and successfully pulled off. The psycho neighbor literally got frozen out of the apartment.
