I always receive 5 stars for the way I treat my guests. I had one very cranky guest who received the same high level of hosting, yet he rated me 3 stars, even after shipping him back (for free) his belongings that he forgot at my place.
It is very unfair, can I ask airbnb to remove the review, inline with the communication I had with the guest, which is available on airbnb?
Of course you can ask Bogy but I do not see where the guest even made bad comments and I highly doubt they will remove his review. Not all guests will think you have a five star listing because some have extremely high expectations or are just a type of person who refuse to give 5 stars as they may think 5 stars means "perfection". I think you just need to move on @Bogy0.
Also, you may have already had the review removed as it looks like you have 5 stars across the board.
