@Kelli405 A few thoughts:
Hopefully the stay is short. One of the reasons we do short term rental is that any bad guests are soon gone.
Just bite your tongue and smile at the guest THEN when they leave you put in an honest (and in this case bad) review. We have only had to do this once.
On the patio smoking I wonder if the guest knows this is against the rules - Many believe that smoking bans only apply inside the property. We actually allow folks to smoke on our patios.
