@Antonio2969 I am guessing that you want to avoid local people booking to avoid potential ‘Party’ scenarios etc. ? As @Mike-And-Jane0 stated, Airbnb do not allow discrimination of any kind and I am unaware of any filter you can put in. However, you could have a minimum age requirement, a cap on guest numbers, tighten things up on your ID requirements and also have guests request or enquire about bookings rather than use Instant Book.
