The new partner program for non-hotels is one of a number of new initiatives to improve its relationship with the private accommodation community of professional managers.

One of the new services to be introduced is a quality rating system ("first-of-its-kind") that Booking.com hopes will become as widely recognized as those used to benchmark hotel properties. Piloted since earlier this year, properties have been designated into five stars based on a number of factors, such as location, size and facilities.
