ok since it was bugging me i scanned through a couple episodes and by the looks of it my not-a-real-answer answer was right except for the kitchenette and conference room being switched which you were right about.

the room they're all working in when foggy asks karen to bang on the router/they're looking over wesley's stuff is the same room they take mrs cardenas into, so it all does happen in the conference room.

the real estate agent says it has "a reception area, a conference room and two offices" so if you add the kitchenette it's all there.
