Zalman Biederman was a horrible landlord. Didn't respond to any bedbug notifications. Did the absolute bare minimum when it comes to treating them. IF HE OWES YOU MONEY, he will dodge you and block your number.
DON'T EVER slip up on your accounting w/ him. He doesn't have an office and prefers to work out of his Rolls-Royce.
Apt is riddled w/ bed bugs and landlord is doing a shit job taking care of them.
