"non-smoking room" smelled like an ashtray.
I stayed at this hotel in early August 2012. I arrived at about 2:20 am because I was on a late flight. I had a confirmed reservation, but it took the desk clerk about 20 minutes to check me in. He seemed to be confounded by the computer. I checked (as I always do) to make sure it was a non-smoking room. He said "All our rooms are non-smoking now." When I finally arrived at my room it was just before 3 am. The room smelled like an ashtray. I was so tired, and didn't want to endure another 20 minutes of trying to change rooms, plus move my suitcase. So I decided to just deal with it. The night was pretty miserable. I had to keep a sheet over my head to avoid the odor of old, stale smoke. I realized that, although "all the rooms were non-smoking" this must have been, for a long time, a smoking room. It isn't possible to simply put a non-smoking sign on a door and call it a non-smoking room. 
I mentioned this to the desk attendant when I checked out the next morning, and asked for someone to call me. I heard nothing. My sister stays at Homewood Suites quite regularly on business, and we have always been satisfied before. We have even stayed at this hotel before, perhaps back when they truly had non-smoking rooms. It was very nice, which is why I returned. But I ended up paying a lot for a room that was very uncomfortable for me, and I slept poorly. 
I often receive a survey after a stay; this time I did not. So rather than fill out a survey, I am hoping to express my dissatisfaction this way.
