There are 2 or 3 cheap-looking motel-type places in Crystal City. One is called the Americana right on US1, and the other is further north out by where Crystal City turns industrial. You can easily walk to both from the metro, or all the way from the airport.
Edit:That other one is called the Crystal City motel, btw.
