@Michelle2532 By the same token, you can say anything privately to a guest, as well.
I took a look at your profile page to see what the reviews were like.
You need to stop responding to positive public reviews by mentioning things guests told you in private feedback. If guests were kind enough to leave a positive public review, you are only hurting yourself by leaving responses about complaints or suggestions future guests would never know about.
Your responses appear on your review page, not the guest's. They are not to be used to attack the guest. They are used to correct misinformation or misleading statements in the public review for the benefit of future guests reading your reviews, or to indicate that a legitimate issue mentioned in the public review has been corrected.
When guests give you private feedback, it should remain private. Message them back about it if you choose, but you need to develop a thicker skin. Most hosts take private feedback on board graciously, especially when the guest has left a positive review, as the guest obviously felt it was something that could be improved on, but didn't want to call you out on it publicly. Perhaps it's something trivial or silly, or was actually a result of them not bothering to read the listing info or communicating with you about something that could have been easily dealt with at the time. Or perhaps it's something that a host does need to consider and change. In any case, do not use public responses to talk to the guest about it.
And even if a guest is negative in a public review, remember that you are leaving responses for the benefit of future guests. So if a guest has a public complaint that was due to them not reading the listing info, or your messages or instructions, a proper response would read, "It's unfortunate that XX did not read the directions she was given for accessing the unit. Had she done that, she would not have had any confusion or difficulty in finding the entry door".
A response like that tells future guests that there is no problem with access, and that guests should not ignore the instructions they are given.
