Hi @Fausto106 ! Guest Favorites are a collection of the 2 million most loved homes on Airbnb based on ratings, reviews, and reliability data from over half a billion trips.
Guest Favorites have a history of positive reviews and are rated above 4.9 stars on average. They have a superb record of reliability, with Host cancellations and quality-related customer service issues of 1% on average. And nearly two-thirds of them are hosted by Superhosts today.
For Guest Favorites, Airbnb focuses on the signals that have the loudest guest voice. A mix of factors are considered in determining whether a listing qualifies as a Guest Favorite, including: overall and subcategory ratings, feedback left in guest reviews, Host cancellations, and the number of quality-related customer service issues. All of those combined create a score that will determine whether the listing qualifies as a Guest Favorite.
I also wanted to share this article that gives an overview of the new Guest Favourites: Most-loved homes according to guests badge.
Regarding your concerns mentioning seeing it for other listings regardless of 4.9 ratings, also clarifying that the average rating for all Guest Favorite listings is 4.9. While these listings generally have very high overall ratings, please note some may be above 4.9 and some may be below.
I hope this helps!
