Hi Lizzie,
It seems this topic has come up multiple times over the past year or so, and nothing has been done about it.
This seems strange as it is clearly a vast majority of people that do NOT smoke, and are looking for NON-smoking accommodation. However we are forced to wade through hundreds of listings to find the ones that are non-smoking. I usually even contact the host, just to be sure as we travel with our kids mostly and so definitely don't want smoking.
Since there is already a smoking allowed filter, it would be beyond trivial to also add a 'non-smoking' filter.
So why hasn't it been done?
I'd like a clear answer from you as to when (not if) we can expect this essential filter to be available ?
Please let us know !!
Alternatively, please open up your API to third party developers, as I'd be happy to write the filter myself.....
Marc
