Well, heres the update..

The old owners(the property has been sold) sent memo's stating the basic common sense items, be quiet, don't park on the lawn, throw trash in the dumpster, ect.. That seemed to work utill the building was in limbo(about 30 days) while being sold. Seems the 'brother' of the neighbor upstairs had a verbal confrontation with the guys that lived across the hall about heat,noise,parking.. the young guys couldn't hang and told the owners(old) that they moved. The brother of the neighbor has since squatted the apartment. with(apparently) his girlfriend.. Both losers by most any definition i can visualise.
And the new owners are now proceeding with eviction on that end. But low and behold the almighty Karmatron!! The police showed up this evening(8ish pm local time) and arrested both squatters.. Not for that mind you.. But for... LOL gotta love this one.... Domestic Disturbance! and pissing off the cops that showed up.....
So now they have the property owners info that i had added to the case file(it's good to 'know' some cops). And, if i'm lucky, the door will be rekeyed in the AM to solve the problem for good(well, untill the upstairs neighbor does something equally stupid like break in). Then the problem may be solved by her eviction as well.... And then maybe the all night traffic and noise will end untill they rent to college students... LOL
