Just ignore her. No need to sleep on the couch. Or look at them. Looking is still attention. Making a loud noise to stop her is still attention. You coming back downstairs to sit on the couch is still attention. Her barking has been rewarded. And it is perfectly normal for a new dog to bark and whine for attention. Its a new home, and they're seeing what the rules are. You've shown her the rules are if she barks and makes a fuss, someone will come out and look at her!
