Went to assigned room to discover it smelled strongly of cigarette smoke. Returned to front desk only to be told by the young desk clerk, “Oh, we have a spray for that.” I explained that a spray would be no help for my asthma. A more seasoned clerk quickly intervened and assigned a new room which was better, but still smelled of smoke. Luckily third time (and last room available) was okay smoke- wise. There was a connecting to next room thru which we could hear the people talking. Overall, while hotel currently nonsmoking, smoke smells clearly not erradicated from previous smoking rooms.
