Practical details and location
The practical details
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.
Evidence by area
All eight areas, in the order this index reads them. Every line was read and placed by a person.

In their words: “The water at Rancho Mastatal is potable, clean and delicious. Please do not bring a disposable water bottle to the Ranch unless you plan on taking it with you when you leave.”
Light Rhythm
Not published. We looked and found nothing on this, which is a gap in what we could read, not a finding about the building.

In their words: “We have over 30 covered structures that make up the Ranch infrastructure a number of which are sustainable homes. Aside from two buildings that we renovated upon arriving to Mastatal, we have designed and built all of our structures.”

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.
