If after any guest stay, you write an email to simply say thankyou and focus on positive aspects of their conduct, you are likely to get a positive private reply. If you are unsure of how they experienced you or your accommodation you can ask their opinion or a general comment, such as I hope that you had everything you needed and expected.... whatever suits your situation. In the case as you have described, this would act as a preventative measure to balance out/reduce cultural misunderstandings prior to reviews being written.
You can add a public response to their review to balance out/ or cancel the negative effect of your review.. reading more reviews helps to understand which comments and topics are reasonable for inclusion in comments.
I hope this is helpful to you and others.
