Stayed during a work conference. A lot of construction, but that is understandable due to it being the off season. However took the stairs from the first to second floor often with the elevators very busy since a lot of colleagues on the same schedule. The stairwell filthy with food trash, gum on floor and spilled drinks on stairs. Made comment to front desk on day two and never corrected leaving day six. Disappointing as a Hilton Honors member.
