What is not publishedthe gaps we looked for and did not find
Nothing is published by the property on EMF Harmony or Sound and Sensory Ecology; what stands on those rows is our own August 2026 site assessment, disclosed as such on each claim. Across the published record the claims are specified rather than measured: named systems and suppliers, not test results.
Regional context2 public figures about the area, none of which scores
Public data about the surrounding area. None of it contributes to the score, because a property cannot be marked down for the conditions outside it.
- Safely managed drinking water, Indonesia: The World Health Organization reports 30 per cent of the population nationally, 35 per cent in urban areas, 24 per cent in rural areas using a safely managed drinking water service. This describes the country, not this property, and says nothing about what reaches a guest room here. It is recorded because it is the background against which a property's own treatment is worth publishing. Source
- Ambient PM2.5 and PM10 near Sayan Ridge, Ubud, Bali, Indonesia: Modelled ambient air over this location averaged 18.7 micrograms per cubic metre of PM2.5 and 21.6 of PM10 across the 720 hours to 2026-08-17, peaking at 52.7 PM2.5. The World Health Organization annual guideline for PM2.5 is 5. This is the outdoor air over the area, modelled rather than measured on site, and it is not a reading of the air inside any room. Source
Not published is not unsafehow to read these scores, and what this index does not promise
A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.
These scores measure disclosure. These scores describe disclosure, not property quality. This index has no commercial relationship with the properties listed unless a badge on the listing says otherwise.
Conditions change, and we will not always know. Every record is a snapshot of what a property had published when we read it, and that date is on the page. Conditions change: a property can refit, change suppliers or replace a system at any time, and nothing requires it to tell us. We re-read records and ask properties directly for updates, but there will always be a gap between what is true today and what was published when we looked. Use this as a frame of reference for what to ask, not as a substitute for asking. Take your own questions to the property before you book, and tell us if you find something we have wrong.
We report what properties publish. We do not inspect, certify or vouch for any property on this index unless a listing says we assessed it on site, and we accept no responsibility for decisions made or outcomes experienced on the basis of what you read here.
