It's still in the same location it always is (for her; the Mansion would never be so gauche as to move a room's location around on Susan) but, as previously established, it now connects directly, through an inner door, to her and Lancelot's bedroom - which is one floor up and two halls over. That inner door is ajar; Susan shoos Regina from the couch and back through the door before closing it firmly.

Then she turns and faces Bacchus. "Welcome to my antechamber," she says. This is mostly a joke, but Bacchus shall be forgiven if he doesn't recognize it as such.
