@Ng16 you can organize a birthday party in a bar, restaurant or you can ask some of your friends if they are willing to let go of their home to throw a party. Airbnb apartments are not a place to do that, there are of course Airbnbs that allow parties but they are much more expensive than a regular apartment and that is for a reason, no one can predict the way the party is going to turn out of if you will clean good enough. I would suggest not to waste your time on Airbnb and find a space more appropriate for hosting a party than some strangers home.
