Tickets to the sex party have now sold-out. However, many families living in surrounding apartments are less than enamoured.
"It does not belong here. I don't have anything against people having sex or changing partner but I think it is too close to small children and families," says resident Louise Carlén to SVT Öst, one of a number of unhappy residents.
Swingers club Adam & Eva arranged the sex party, which is to be held at the Arbis Theatre on 19 October. The club's original venue by Norrköping's harbour, burnt down last spring. All swingers attending next month's event, called "Eyes Wide Shut", must wear a mask and cape.
Theatre property owner, Robin Karlsson, sees no problem with the arrangement.
"If someone calls and says " hey, I want to buy 300 tickets " or " hey, I want to rent a 40 square meter room " then I am not going to ask " and who are you sleeping with ? " I cannot , I cannot and I will not do it".
SVT Öst found that not every local is against the sex party, especially those who have appeared on the Arbis stage before.
Pensioner Lennart Holmqvist has featured in many operas and musicals over the years and lives above the theatre.
"If they want to go down into the basement there and have sex, then let them do it," he says with a laugh.
