Scents of Belgium...

I'm staying in a hotel in Washington D.C., and no joke, the entire hotel smells like sewage.  It's a Sheraton, and I've stayed here every year, and it usually smells like someone blew up an air-freshener factory, but this time, the whole place smells like raw sewage.  I even checked out the other floors.  It's overpowering.  The front desk says they had some plumbing problems a few days ago, but no one has reported anything since then.  They say they can't smell it, but several other guests I've asked all said they can smell it strongly too. 

The scent is definitely reminiscent of Belgium, where the concept of "drain" is still under research and development.
