I have been a guest at the HIE Texarkana Tx for over a week. It's very new, very nice, with great service most days. One concern that gives this hotel my low grade is air quality. The ventilation in this room is poor. The moldy smell comes from of the air conditioning unit whenever it pushes out cold air. The smell was vague when I first checked into the hotel but is now very noticeable. The air quality is now so low that I have to turn off the air conditioning unit entirely and wait for a maintenance person to come check oh the air conditioning system. When I called down to express my concern about the air quality in my room, the desk clerk told me that the "paper mill was especially bad tonight." As if the air quality issue wasn't bad enough. I assured the desk clerk that "it was also an air quality issue and I was definitely smelling mold." I hope HIE can resolve the air quality issue because I would rather improve what's wrong with the room than checkout altogether. Aside from the ventilation and air quality issues, the room is impeccable.
