Yes. I think you should send the guest a professional message asking them to elaborate on their choice of star ratings so you can "improve." What do you have to lose? I also don't see anything wrong with messaging the AC lady. "XX thanks for your review. I'm glad you enjoyed your stay. I'm sorry if you were surprised by the window AC units. I try to make this clear in my listing description so there are no surprises. Wishing you all the best."
Just make sure that you don't click the "reply" to the review button. Send the message in the direct message thread.
