i am at Vistana right now and there are no smells but you can arrange for them to put an ozone machine in the unit before they come to purify it. at least i think it is called an ozone machine. just call customer relations and tell them what you want and then put it in the diamond request too. even though i used the diamond lane, i called also. It turned out that the customer service rep was better at getting me what i wanted than diamond lane. He put it right in the computer. by the way i am using my husband's lap top and the keyboard is not as good as mine so excuse typos
