@Aarón10 Airbnb reviews stay with the profile the listing was under and can't be transferred. That's because reviews are really reviews of the host, not the property. You could have the nicest place on earth and still get bad reviews if the host or co-host (whoever was hands-on with the guests) was inattentive or rude. Conversely, you could have a very modest, no frills listing, but provide a guest experience that leads to glowing reviews.
If what you mean by "I worked hard for those reviews" means you dealt mostly with your guests, and the co-host just filled in sometimes, or handled some aspects of hosting for you, then it is indeed a shame that you allowed him to set things up to his liking, rather than yours. Tough learning experience, but I'm sure you'll bounce back.
