The room smelled like sewer gas or car exhaust. I ran water in the shower and that seemed to eliminate the smell. Air return filter was way past the time to change it. The room and beds were lovely but I need better lighting. Not enough choices for tv viewing. Lotions and soaps were nice. Loved the scent.
