I just received a request to book my place for 8 days. The problem is, that the guests decided to bring a child with them, because it says in my listing that no charge for extra people and Family-friendly, although the listing is described as a provate room for up to two guests. I can actually understand their position - this phrasing is really not clear. I would simply want to delete the box of extra people because it is causing a confusion... I tried to put a very high pricing for extra guests like someone has suggested here, but the box is still there...
@Idan0, did you remember to hit the Save button once you'd added a high nightly fee?
I'm not able to see your listing on my Safari browser, but would suggest that you state clearly in your Space description that the accommodation is not suitable for a child.
In your shoes, I would consider declining the request for the above reason.
