How we built this report
Every figure in this report was compiled in July 2026 from named, public sources and verified against the original before publishing.
- Compiled from primary sources
Figures come from consumer and guest surveys (Wander, Ecolab), platform review-mining (TrustYou), a peer-reviewed academic analysis of TripAdvisor reviews (IJEMR), a large public-complaint study (Asher Fergusson), and operational field data (Breezeway).
- Only explicitly stated figures
We include only numbers a named source states directly, and attribute each one inline at the point it appears. Where a source published a volume but no percentage breakdown (Breezeway), we cite only the volume.
- Methods and samples shown
Survey sizes and study designs are stated alongside each figure (for example, Wander's 1,000+ respondents, Ecolab's 598 guests, and the IJEMR study's 127 analyzed reviews) so readers can weigh them.
- Independent review
Written by Sam Parks and reviewed by co-founder Rohan Nagabhirava before publishing.
Note: several figures come from vendor-commissioned surveys and review-mining, and the Asher Fergusson study measures publicly tweeted complaints rather than the full population of stays. Sample sizes and study types are stated inline; read each figure with its method in mind.
What guests complain about, by the numbers
All 25 figures in this report, grouped by theme, each drawn from a named public source and independently verified before publishing.
The complaint mix: what guests flag most
Across every dataset, one problem leads: cleanliness. According to a January 2026 Wander survey of more than 1,000 US travelers, 45% of disappointed guests named cleanliness as their primary frustration, and a peer-reviewed 2026 analysis of TripAdvisor reviews in the International Journal of Economics and Management Research found cleanliness deficiency behind 69.8% of negative reviews. TrustYou, which analyzed reviews across more than 50,000 hotels, found one in four of all guest reviews mentions cleanliness at all. Maintenance (Wander, 31%), misleading listings (Wander, 30%), and noise (IJEMR, 44.4%) follow, while the Asher Fergusson study of 127,183 public Airbnb complaints maps the safety tail.

Asher Fergusson study (2021)
What this means: the pattern is consistent across surveys, platform review-mining, and peer-reviewed analysis: cleanliness is the number-one thing guests complain about, with maintenance and misrepresentation close behind. These are precisely the conditions a turnover inspection exists to catch before a guest ever sees them.
What a complaint costs: ratings and rebookings
A complaint is not just a bad mood; it moves the score. Ecolab's November 2025 survey of 598 hotel guests quantified the penalty by defect: odor drives 84% of guests to cut their rating by at least two stars, visible pests push 72% to cut it by three or more, and stained linens send 73% to a two-star-or-lower rating. According to TrustYou, more than half of hotels saw their yearly performance score dented by room-cleanliness complaints in 2020 alone. The Wander survey adds the guest-side cost: 52% of disappointed travelers said the issues disrupted their trip.
Statistic 11
Odor drives 84% of hotel guests to lower their satisfaction rating by at least two stars.
Ecolab survey (2025)
Statistic 12
Visible pest evidence makes 72% of guests reduce their rating by at least three stars.
Ecolab survey (2025)
Statistic 13
Stained linens lead 73% of guests to give a two-star rating or less.
Ecolab survey (2025)
Statistic 14
54% of guests who saw stained linens said they would reconsider a return stay.
Ecolab survey (2025)

Mold or mildew in the bathroom makes 60% of guests consider a different hotel next visit.

Statistic 16
More than half of hotels saw their yearly performance score dented by room-cleanliness complaints in 2020.

Statistic 17
Over half of disappointed guests (52%) said rental issues disrupted their trip.
Wander survey (2026)
Statistic 18
One in four (26%) called the issues minor but still disruptive; 4% said the rental ruined the vacation entirely.
Wander survey (2026)
What this means: the penalty is specific and steep. A single visible defect, an odor, a stain, a pest, does not cost a fraction of a star; it costs two or three, and often the return booking. That makes the last-mile check before check-in the highest-leverage moment in the whole turnover.
Expectations versus operational reality
The gap between what guests expect and what a turnover actually catches is where reviews are won or lost. Cleanliness is not just the top complaint, it is the top booking factor: 45% of Wander respondents ranked it above price, amenities, and even location. On the praise side, the IJEMR study found cleanliness and comfort the second-most-cited driver of positive reviews (81.3%), behind staff service (90.6%). And the operational scale is real: Breezeway reported analyzing more than 300,000 issues logged by inspectors, cleaners, and field staff through its app, drawn from a study of 127,183 public complaints on the guest side.
Statistic 19
Cleanliness is the single most important factor guests weigh when booking, chosen by 45%.
Wander survey (2026)
Statistic 20
Cleanliness ranked highest among booking factors, ahead of price, amenities, and location.
Wander survey (2026)
Statistic 21
Staff service quality was the top driver of positive hotel reviews, at 90.6%.
IJEMR peer-reviewed study (2026)
Statistic 22
Cleanliness and comfort was the second-most-praised factor in positive reviews, at 81.3%.
IJEMR peer-reviewed study (2026)
Statistic 23
Breezeway reported analyzing more than 300,000 issues logged by inspectors, cleaners, and field staff.
Breezeway (2025)
Statistic 24
The Fergusson study analyzed 127,183 public Airbnb complaints posted between 2015 and 2020.
Asher Fergusson study (2021)
Statistic 25
The IJEMR analysis drew on 127 TripAdvisor reviews (64 positive, 63 negative) across 15 star-rated hotels.
IJEMR peer-reviewed study (2026)
What this means: guests weigh cleanliness above everything when they book and reward it when they review, yet issues pile up by the hundreds of thousands in the field. The distance between that expectation and day-to-day execution is exactly the gap condition documentation is built to close.
