Review doesn't add up. Is there anything I can do.

[Bob216]

I've prided myself on only getting 5* reviews.  Today I noticed that airbnb is showing a 4.99 rating on my listing.  When I dug in I found one guest gave an overall rating of 4, with 5 in every sub category.     Is there anything I can do about this?  Should I message the guest?

Thanks

Bob

No one really cares whether you are 5 or 4.99 or 4.8 after close to 100 reviews, but they certainly do about reviews. Those matter and excellent ones you do have.  Sooner or later some guest will not understand the star system and that is what makes almost impossible to stay at 5 forever.
