Practical details and location
The property’s own website
The property's own site: its name and its place are on the page
Safely managed drinking water, Indonesia, 2024: 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.
Regional data is context about the location. It does not establish conditions inside a room.
Ambient PM2.5 and PM10 near Sumba, Indonesia, 30 days to 2026-08-17: Modelled ambient air over this location averaged 9.6 micrograms per cubic metre of PM2.5 and 13.3 of PM10 across the 720 hours to 2026-08-17, peaking at 19.8 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.

In their words: “It includes over 20 buildings in total, with different structural systems and uses amongst them.”
Bamboo Pure, the company that built this campus, publishes on its general bamboo supply page, which does not reference this campus, that its bamboo is treated in a borax based solution, a named preservative chemistry, with no residue or emission figure given.
In their words: “Our bamboo is treated in a environmentally friendly borax based solution.”
The same supplier publishes that it tests its treatment solution and poles at a laboratory on a regular basis, naming no laboratory, standard, result or interval.
In their words: “We test our treatment solution and our poles at a labratory with international standards on a regular basis to ensure they all meet minimum treatment standards.”
The property publishes that the bamboo used on its campus is locally harvested, ecologically treated and then lab tested for durability, naming no chemistry, laboratory, standard or result.

The property publishes a single use plastic free purchasing policy binding all departments and suppliers, with papaya straws and bamboo toothbrushes given as guest facing substitutions, and no material specification for either.
In their words: “We have implemented a 'Single-Use Plastic Free Purchasing Policy' that all our departments and suppliers must adhere to.”
Food and Kitchen
The foundation's own 2023 impact report gives a monthly harvest figure of one tonne of fruit and vegetables from the on site permaculture garden. This is gross farm output rather than the share of guest food it covers, no denominator is published, and the report names no external auditor or method, so it is recorded as specified rather than measured.
In their words: “we are now able to harvest 1 tonne of fruit and vegetables every month.”

Disclosures
Compare what each stay offers, how it was checked and what still needs confirming. Assessment labels describe the review, not an overall quality rating.
A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.
A score describes proof: what a stay publishes and, on a Human Garage certified stay, what our assessor checked in person. It is not a quality rating of the property. Listings are free, and any commercial relationship is disclosed.
