Will my Airbnb or VRBO reviews still show up on Houfy once I remove my listing from these platforms?

Your reviews will stay on Houfy once you remove your listing from Airbnb or VRBO. Nothing removes them automatically.

If you would rather not keep them, you can remove them yourself. Open the listing, go to its Reviews tab, and use Remove next to the imported Airbnb or VRBO link.

This clears every review that came in from that link and removes the link at the same time. It applies to all of them at once, your listing loses the review count and star rating those reviews carried, and the only way back is to import from that platform again - which will not be possible if you have already taken the listing down there.
