- Specified
The building control installation is published on the KNX Association project database, and the heating, ventilation and air conditioning functions listed as in use include carbon dioxide and humidity measuring, natural ventilation and individual room or zone control. The record was submitted by the system integrator ETHNOKAT S.A., which the project's Archello listing credits as construction. No filter grade, fresh air supply rate or any published reading accompanies the listed measuring function.

What is not publishedthe gaps we looked for and did not find
Air. No filter grade, fresh air supply rate, mould protocol or published carbon dioxide, particulate or volatile organic compound reading was found. The KNX project record lists carbon dioxide and humidity measuring as an installed function, which names a capability rather than a result. Two combustion related facts are recorded here rather than credited: the property publishes that smoking is prohibited in all rooms, suites and indoor and outdoor common areas, and the salt room page describes salt particles being breathed in from the air of that room, with no halogenerator, salt or air specification named. No fireplace or wood fired appliance was found published. Water. This is the largest gap on the record relative to what the property is built around. No water source, treatment train, filtration specification, contaminant panel or laboratory is published, and no mineral analysis of any kind was found. The Sanctuary Deprivation Pool page publishes two properties of that pool's water, that it is held at body temperature and that salt is added until the body floats. Neither is given as a figure, and neither is a source, a treatment or a test. Beyond that and a statement of compliance with an unnamed legal framework, nothing is published on pool, hammam or hydrotherapy sanitation chemistry, and a capacity rule of one swimmer per five square metres of water surface, which is a bather load figure and not a water measurement. The spa's water facilities are published as facility names only: the 25 metre Waterwell with hot and cold Kneipp footbaths, the Byzantine Hammam, the sphere pool at four metres deep at its centre, an infinity outdoor pool, Watsu and deprivation pools, cold plunge, ice fountain and experiential showers. How drinking water reaches the guest is not published; the health and safety page refers to water bottles being disinfected, which describes handling rather than source or treatment. Light. The published colour temperatures, tunable white fittings and daylight sensors are for spa spaces. No guest room lighting specification, blackout provision, flicker performance or exterior lighting discipline is published. Electromagnetic. The property publishes free Wi-Fi in the reception area, rooms, spa and restaurant, which is a coverage statement and not a disclosure either way, and it publishes a prohibition on mobile phone conversations, which is behavioural. The KNX record is the only topology fact found, and it covers the building control network rather than the guest data network. No shielded cabling, demand switch, access point or meter placement, or field measurement in a sleeping area is published. Materials. No linen or textile fibre content, no textile certification such as GOTS or OEKO TEX, no mattress maker, no paint, adhesive or sealant emission class, and no cleaning or laundry chemistry is published. Bathroom amenities are published as the property's own scented preparations adapted from Greek recipes, with no formulation or allergen list. Food. The restaurant states that it knows its farmers, producers and winemakers by name, and none of those names is published on the page. No share of supply from the garden, no cookware, no kitchen or ice water specification and no additive or allergen position is published. The ISO 22000:2018 food safety policy is recorded in the standards block rather than scored, and it names no supplier or sourcing requirement. Sound. No measured background noise level in a guest room, no acoustic separation rating between adjoining keys, no mechanical or plant noise figure and no fragrance policy is published. Sound is published in two directions, added in the sphere pool and reduced in the Sanctuary Deprivation Pool, and in neither case with a level, a system or a means of declining it. Scent is published as something the spa adds, in the aromatherapy amenities, on the same terms. Standards. No third party building, environmental or wellness building standard was found published for the property. The affiliations shown on the site, including Small Luxury Hotels of the World, Virtuoso, Healing Hotels of the World and the Michelin Guide, are booking and consortium memberships rather than standards.

Useful context. A held standard does not move a pathway score on its own. It moves a score only through the evidence that standard publishes.

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, Greece: The World Health Organization reports 97 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. Source
- Ambient PM2.5 and PM10 near Mystras, Peloponnese, Greece: Modelled ambient air over this location averaged 7.8 micrograms per cubic metre of PM2.5 and 14.4 of PM10 across the 720 hours to 2026-08-17, peaking at 17.6 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.
