Bardessono Hotel & Spa
6526 Yount Street, Yountville
The stay
Salvaged walnut, cypress and stone, a short walk from Yountville’s restaurants.
Bardessono says it was one of the first hotels in the country to reach LEED Platinum, and it wears the claim lightly.2 Floors are walnut from retired orchards, desks are slabs of salvaged bay laurel, and the grounds are planted with native, drought-tolerant species. It sits in the middle of Yountville, close to the restaurants that made the town’s name.
The hotel says it was built with non-toxic, non-allergenic materials and that its restaurant and spa buy primarily from local organic or sustainable producers.2 Its Pure Wellness suite adds in-room air filtration and allergy-friendly bedding, but it also uses anti-viral and anti-microbial surface treatments, and several suites have gas fireplaces.1
It is a strong choice for materials and design. If you are sensitive to biocides or combustion, ask for a suite with neither.

What we love
- Salvaged walnut, cypress and bay laurel throughout.2
- LEED Platinum, by the hotel’s account one of the earliest in the United States.2
- A kitchen and spa sourcing primarily from local organic producers.2
Worth knowing
- The Pure Wellness suite uses ‘anti-viral & anti-microbial treatments’.1 Guests avoiding biocides may prefer a standard suite.
- The King Spa, Tufa and Accessible King Spa suites have gas fireplaces.1
- The non-toxic materials claim is the hotel’s own; it does not list specific products.2
- The Pure Wellness suite’s ‘allergy-friendly bedding’ and mattress encasements are described, but not pillow covers or how bedding is washed.1

Air
What you breathe for eight hours a night: smoke history, fresh air, filtration and anything burning in the room.
Smoke-free property

Opening windows
Not yet reviewed.
Filtered fresh air
Not yet reviewed.
In-room air purifier
Not yet reviewed.
So far, the hotel says: The Pure Wellness suite’s in-room air filtration ‘removes up to 99.99% of pollutants and allergens, exceeding HEPA standards’.
Our note. The device, and whether it emits ozone, are not stated, so this falls short of the criterion.
How we know
What we look for. A true-HEPA purifier in the room or on request, with no ozone-generating or ionizing function.
Why it matters. Portable HEPA units lower indoor particle levels, which matters most during wildfire smoke. Ionizers and ozone purifiers can add an irritant gas instead.

No in-room combustion
Not metin some rooms or areas
The hotel says: The King Spa, Tufa and Accessible King Spa suites each have a gas fireplace.
Our note. The fuel of the Olive suites’ patio fireplace is not stated. Ask for a suite without a fireplace.
How we know
What we look for. No gas fireplaces, candles or incense in guest rooms.
Why it matters. In homes with gas appliances, the US EPA notes that indoor nitrogen dioxide often exceeds outdoor levels, and that it irritates the eyes, nose, throat and airways. Candles and incense burn in the same small, closed room.

Cleaning & care
How a room is cleaned, treated and prepared, and whether a request for a gentler clean is actually honored.
Low-chemical housekeeping
Not yet reviewed.
No ozone or biocide treatments
Not metin some rooms or areas
The hotel says: The Pure Wellness King Spa Suite has ‘specialized anti-viral & anti-microbial treatments’.
Our note. Standard suites are not described as treated; guests avoiding biocides may prefer one of them.
How we know
What we look for. No ozone shock treatments, disinfectant fogging or residual antimicrobial coatings in guest rooms.
Why it matters. The US EPA warns that ozone generators can raise indoor ozone to levels that harm the lungs, even when used as directed. Residual biocide coatings add a chemical exposure with little benefit to a healthy guest.

Allergy-friendly rooms
Not yet reviewed.
So far, the hotel says: The Pure Wellness suite has ‘allergy-friendly bedding’ and ‘special mattress encasements’.
Our note. Pillow covers, feather-free bedding and hot washing are not mentioned, so this falls short of the criterion. The encasements are described as treated to reduce allergens, which suggests a chemical treatment.
How we know
What we look for. Allergen-barrier mattress and pillow covers and feather-free, hot-washable bedding, in all or designated rooms.
Why it matters. For dust-mite allergy, US health guidance is to encase mattresses and pillows in allergen-proof covers and wash bedding weekly in hot water (130–140 °F, about 55–60 °C).

Food
Allergen care first; where the produce comes from second.

Not yet reviewed.
Garden or organic produce
Hotel-reportedacross the property
The hotel says: ‘Products in the restaurant and spa are sourced primarily from local organic or sustainable producers’, with produce from the hotel’s gardens.
Shown for information; not scored.
How we know
What we look for. A meaningful share of the kitchen’s produce is grown on site or certified organic.
Why it matters. A large review found detectable pesticide residues about four times as often in conventional crops as in organic ones. Over a short stay the difference in exposure is small, so we show this as a note on the kitchen, not a scored health factor.

Building
The materials a hotel was built and renovated with, how it handles damp, and what third parties have certified.
Low-emitting materials
Not yet reviewed.
So far, the hotel says: ‘Non-toxic, non-allergenic materials were used in construction.’
Our note. Paints, adhesives, finishes and flooring are not named, so this falls short of the criterion.
How we know
What we look for. Low-VOC paints, adhesives, finishes and flooring specified in construction or renovation.
Why it matters. Paints, varnishes and adhesives release volatile organic compounds, formaldehyde among them, most heavily when new. Low-emitting products reduce that load.

Building certification
Hotel-reportedacross the property
The hotel says: It is certified LEED Platinum.
Our note. Not yet checked against the USGBC directory.
Shown for information; not scored.
How we know
What we look for. A third-party certification such as WELL, LEED or a green business program, recorded with its level, and its year where the certifier gives one.
Why it matters. WELL assesses air, water and light in occupied buildings. LEED and green business programs are mainly environmental, with some indoor-quality elements. A certificate records what was designed or checked at a point in time, not what a room is like today.
