This new feature is unnecessary and doesnt add value for guests and further punishes hosts in an already flawed star system.
Response from Airbnb
Based on feedback from the host community, we decided to terminate the Lowest Review feature. The intention of this feature was to help set guest expectations for a stay by highlighting aspects of past experiences that did not go well. However, your feedback helped us understand how sometimes a review can unfairly represent the experience that you will provide future guests. Though this feature was not the best approach, it’s still a priority of ours to ensure travelers see the reviews that accurately capture what it’s like to stay in your place.
