The reason to stay here is to be right near Newark airport, so you can expect the area to be pretty grungy. Building is older, but rooms, while not luxurious, seem to have had a total refresh in the recent past. Rooms are kept quite clean, while common areas not so much.
Breakfast is decent - the omelets are even made from real eggs, not powdered.
Staff is always available and friendly, and shuttle service is prompt, helpful, and available 24x7.
