What does this trust score mean?

The StayRadar trust score is not an average of star ratings. Some guests may leave a high star rating while describing serious issues in the review text; some low ratings may reflect personal expectations or seasonal conditions. StayRadar therefore focuses on recurring strengths, risk signals and pre-booking checks found in the review text, rather than the number alone.
