Hi Bruce.
Being an ex-smoker (gave up 8 years ago) I now can not stand the smell of cig smoke. So I instantly know if someone smokes.
I have a Total no smoking policy in my home. Even state "We are a non smoking household, so can only accept non smokers"
And if this is iggnored the message is repeated when booking,
and in my handbook "if you smoke it is respectively requested you cancel your booking"
I know this may appear draconian, but i do not want my home smelling like an ashtray.
Whether this has effected the number of bookings, I have no idea, I do know that some guests have commented that its nice to have a non smoking household where there is definately no smell of cig smoke.
