@Peter1354
Thanks for response.
However, it's evident that you did not grasp my initial response to your post.
My response was specifically tailored to your response to Emiel, in which you admit you had not familiarized yourself with the Guidelines and T&Cs BEFORE you started hosting!
Therefore, my response was exclusively related to the situation you belatedly found yourself in; and the possible solution, as previously mentioned, that you can request Airbnb delete
the Review. Airbnb will do it depending on the circumstance of disclosure as I described.
I speak from considerable experience.
Your second response that you are happy with the 4.9 stars conveys that you have no intention of pursuing this matter.
I wouldn't be surprised, and should you wish to spend some considerable time perusing numerous Reviews on both Host & Guest profiles around the world, you will find that it is littered with 3rd Party Bookings, mostly knowlingly so, by and large on behalf of friends & family. -- In other words, you'll discover that this is a gray area, and that Airbnb only intervene when called upon.
Finally, re your suggestion: ''I think Airbnb should implement a check box...'
You are welcome to suggest it to Airbnb via their 'feedback' channel.--
Only please know that you wouldn't be the first person to suggest 3rd PB rule should be writ in large at the point of booking, not only for Guests but equally Hosts!
