This neighbor really stinks, a lawsuit claims.

Linda Cohen, who lives on the 17th floor of historic 25 Central Park West, leaves weird notes covered in garlic powder for a rival tenant, smokes enough pot that the smoke seeps into adjoining apartments, and holds “drum circle parties,” according to a Manhattan Supreme Court lawsuit.

The landlord, 25 CPW City Views LLC, is so fed up with Cohen’s alleged antics, including fabricated noise complaints, it is suing her for being a nuisance.

Cohen is fixated on her upstairs neighbor, Hedy Stempler, the landlord charges. She once showed up at Stempler’s door “ringing the doorbell, shouting and then throwing a powdery substance at Stempler and pushing an orange in Stempler’s face,” according to the complaint.

Cohen couldn’t be reached. Stempler declined comment.
