Let me guess, you didn't charge them extra for the daughter?
Newer hosts haven't developed the hosting muscle needed to not get doormat burnout.
It helps to imagine yourself as head of a hotel used to fielding all kinds of requests.
And even turned down requests are done with charm and friendliness, but if it's a NO, there is no negociation.
It helps to peruse this forum. It helps to imagine certain potential situations or requests and how as a hotel person would you field them.
That being said, also remember that even if you are running a little business out of your home, YOU are the owner and YOU make the rules. What helps is to go through things on arrival with guests. You repeat house rules or other important things because guests most often DO NOT READ.
You won't get around talking to them about their entitled attitude. It also sounds as if the daughter is the real guests' speaking instrument. I were you I would go directly to the parents who are your guests.
Try to find a humorous way to do it. But if they 'forget' again the next day, tackle it again.
Doing nothing will encourage those guests prone to hitting on weakness to really rub it in.
Tell them that transportation is unfortunately not part of the booking fee. Can't they use Uber?? This very much sounds like a ploy to see how far they can stretch your boundaries or how well they can walk over you while inhaling the intoxicating smell of the newbie host going far too many extra miles for (undeserving) guests...
And so that they don't slam you with an unfair refund request, keep exchange of critical things on the booking messages. Repeat conversations you had with them face to face. These messages are open to Airbnb and they will look into them if guests make (unfair) accusations. Always stay factual, how you intend to solve things if there was a complaint. Or reminding them of certain issues and again sending the exerpt of your House Rules pertaining to this.
BTW, Instant Book might work for you, and many hosts not renting any part of their own home are happy with it, but you do lose all ability to vet your guests and deciding whether or not they are a good fit. It's usually recommended by experienced hosts not to turn it on before they haven't hosted for quite a while.
