Per the flyers spotted on the block...
"We are a group of tenants living on 6th Street determined to address the issue of noise disturbances occurring every weekend — crowded parties on the rooftop with blasting music and guests yelling until late night."
Apparently, these have become a Friday-through-Sunday ritual these past few months.
There's an email address to receive updates on the group's action... as well as a prompt to file a complaint with 311.
The landlord is Centennial Properties, which is the new name of convicted felon Steve Croman's 9300 Realty.
According to Streeteasy, units range in price from $4,100 to $7,600 for three to four bedrooms. Amenities for a few units include balconies with at least one having a private roof deck.
