Hi:
I understand your concern and frustration. We had a nice review that ended stating the house was lovely but, far away from shopping. Shopping is less than a 1/4 mile away-Thanks. Unusual but we did contact Arbnb and had the review removed. I copied and paste previous reviews that stated how close shopping was. Made note the review in question was damaging to my listing and future tenants and most of inaccurate.
You will however still keep your 5 star's and not saying anything given that your previous reviews mentioned how close the beach is. They won't blink at her's
On the other hand I have done this also. You can reply to their review. "We are happy you enjoyed your visit in our condo. Guest's do enjoy our beach front condo and the salt air. We would be happy to host you and your family on your next family vacation.
Good luck!
