The property's own site: its name and its place are on the page
Safely managed drinking water, Mexico, 2024: The World Health Organization reports 43 per cent of the population nationally 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 Tecate, Baja California, Mexico, 30 days to 2026-08-17: Modelled ambient air over this location averaged 14.7 micrograms per cubic metre of PM2.5 and 18.9 of PM10 across the 720 hours to 2026-08-17, peaking at 32.8 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.

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.
