Such was the overpowering odor of weed I went round back to find the two guests sitting on the steps happily puffing away with the door to the unit open.
'No smoking on the property'
What annoys me is the feeling of paranoia for the host that Airbnb creates - what if they leave bad review etc etc. So now my kids are breathing in clouds of second hand smoke, as are my neighbors, and tomorrow's guests will wonder why the entire place stinks of air freshener.
Airbnb needs to make it clear - break house rules, you will be asked to leave by the host, and do not get to leave a review etc etc. Short term rentals have no occupancy rights, a full refund by the host should allow complete termination
