@Patrick568 I don't see any review on your profile which states such a thing. Did your guests mention this in private feedback? I notice you have made a few responses to your reviews which address things which weren't mentioned in the public review at all. You shouldn't do that- only respond to what is publicly written. By responding to comments that no one else can see, you are simply drawing attention to a complaint that no one would know about otherwise.
Also, responses should only be made to clarify something the guest said in the public review that is untrue or misleading. Responses are for prospective guests, not a rebuttal directed to the guest who wrote the review. So if you are just responding to a nice review, it's fine to address the guest "Thanks for staying, XX, it was a pleasure to host you".
If the guest has voiced a complaint which is valid, " We are so sorry you were disturbed by the neighbor's loud party. We have spoken to them about it and they assured us it won't happen again. The parents were out for the evening and their teenager invited friends over without permission. " "Sorry about the broken bed slat. Had you let us know about it during your stay, we would have come right over to replace it. The bed is fine now."
If it's a complaint which isn't valid, don't engage in arguing with the guest, just make things clear to future bookers. "Had this guest read through the listing description and the amenities offered, he would have been aware that there is no washing machine available for guest use."
