I once sold a film camera that smelt of cigarettes.  I had a lower price on the camera because of the smell.  I had in the description that non-smokers should take this into account and that smokers probably wouldn't notice the smell.

Anyway, the camera sold 5 minutes after it was listed, but mainly because of the cheaper price.

I think that if you sell something and say it is is 'very good condition' and not mention a cigarette smell then some would say the description is misleading through omission of information that a reasonable buyer would consider should be disclosed.
