It can influence reviews, lower ratings and shape guest satisfaction and future bookings.
A recent study shows what guests are saying – learn what issues have the greatest impact on guest satisfaction, reviews and likeliness to return.
A third-party survey of 598 hotel guests conducted on behalf of Ecolab in November, 2025 examines what drives hotel selection, what leads guests to return or not and which factors most often result in negative reviews or reduced guest satisfaction scores.
The findings are clear: cleanliness is one of the top factors that guests use to choose a hotel, and it is one that hotels can directly control.
