Omega: Finding Aria's couch for Harrot side mission

I've played through the DLC Omega a couple of times, and have not been able to find Aria's couch for Harrot.  I have tried searching every nook and cranny in every area along the way, but cannot seem to find it.  Am I experiencing a clitch in the DLC, or is the couch that well hidden?  Any help would be appreciated.
