We've created a tool called "OwnerRez Channel Bridge" which is a Chrome browser extension that gives you extra functionality when working with listing sites. Read about it in our our Channel Bridge Overview article.
This video will show you how you can Channel Bridge to download your reviews data, in detail, from channels like Vrbo and Airbnb and then import that data into OwnerRez. We also have a video showing how to download your booking and guest data from the channels. This video covers the reviews side.
