Turn right or left from the main door toward the master bedroom (depends which orientation you have). Right before you enter the master bedroom, the laundry room door will be on your right or left (again depending on the orientation of the room). If you are in a villa in a bldg numbered 30 or higher, there will be another door in the laundry room that opens up into the master bedroom bathroom (right near the sink). If you are in a lower number building, there will not be a door to the bathroom from the laundry.
Yep, they are full sized. Not stacked. And the laundry room is a real room, not a closet.
