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, Costa Rica, 2024: The World Health Organization reports 81 per cent of the population nationally, 80 per cent in urban areas, 81 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 Peninsula Papagayo, Costa Rica, 30 days to 2026-08-17: Modelled ambient air over this location averaged 5.9 micrograms per cubic metre of PM2.5 and 10.3 of PM10 across the 720 hours to 2026-08-17, peaking at 16.3 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.

Biophilic and Healing Design
The design architect publishes the method used to set the buildings on the site: a survey of every tree, mapped against animal habitats, physical constraints and views, carried out with the landscape architect EDSA.
In their words: “We worked alongside EDSA to survey all the trees, creating a map that plotted these against animal habitats, other physical constraints, and natural assets such as views.”

In their words: “Every stone wall was built by local craftsmen using material sourced directly from the site, and the art and design pieces throughout the resort are by Costa Rican artisans, including the 650,000 hand-laid tiles in the chapel.”

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.
