Thanks for reply.
As mentioned as non IB Host, I've never seen a single score, and accordingly don't consider it a hindrance. It's all about the Reviews if prospective Guest has any, and more so vetting process to my satisfaction.
Thus as mentioned in view of your Review I would address the issue of the open door during Enquiry or Reservation Request. -- Still, my building has 2 doors, door to building and door to flat. I've never experienced anyone leaving both doors open, and so the chances of anyone doing it are highly unlikely. Moreover, I don't have locks to the bedrooms.
Yet, if your Review had mentioned what you experienced within '20 minutes of arrival'., especially the disregard for your introduction and their body language 'leave us alone',
followed by the persistent noise & leaving lights on, I would not have accepted such persons to make a booking.
Indeed, as a live-in host, the single thing that irritates me most is the impersonal response which I've experienced very occasionally, and can't wait for such guests to depart.
