The Guest Experience Index cross references star ratings with written reviews, using a bespoke software created by Olery, to search for keywords which indicate the guest experience across room quality, value rating, service, location and cleanliness.

“The Guest experience index is a tool for the industry to provide a tangible benchmark to measure their service level,” said Filippo Sona, director and head of hotels for the MENA region at Colliers International.

The Guest Experience Index was developed by software development company and travel data analysts Olery, in collaboration with the VU University Amsterdam, and indicates a guest’s general perception of a property’s quality, on a scale from one to 100, with 100 being the perfect top score.

The data includes both hotels and serviced apartments, and can also be analysed for independent, regional and international brands, different star ratings and hyper-local neighborhoods within a wider city or Emirate.
