The hype
The spa and pools are world-class, but the rooms feel tired and overpriced for the level of luxury provided.
Fairmont Sonoma Mission Inn & Spa
$450-800+/ night
Book this if You want the only authentic geothermal mineral spa experience in wine country and don't mind a property that feels a bit 'historic' in both good and bad ways.
Why People Love It
- Natural geothermal mineral pools (135°F from 1,100ft deep)
- Daily complimentary wine tastings in the lobby
- Chardonnay, the resident Golden Retriever and 'Director of Pet Relations'
Quick Take: A legendary spa destination resting on its laurels where the mineral water is pristine but the carpets and soundproofing are showing their age.
Reviewed by @elinaways: I spent the most relaxing weekend here. The suite was incredible—having a huge jacuzzi right in the room changed the game. Between the champagne on the terrace and the caviar dinner, I felt completely spoiled. Perfect spot for a romantic reset.

Reality check
You are paying for the pools and the grounds; if you spend all your time in the room, you will feel ripped off by the worn furniture and noise.
- You prioritize spa treatments and soaking in mineral water above all else
- You are a couple looking for a romantic suite with a private jacuzzi and fireplace
- You love historic, mission-style architecture and lush gardens
Cleanliness & Maintenance
6.5
- Housekeeping: Generally responsive, but reports of missed details like dust in corners or under beds.
- Bathroom hygiene: Functional but dated; grout lines and caulking in older rooms often show age and discoloration.
- Maintenance: A major weak point. Complaints of peeling paint, worn carpets in hallways, and 'dingy' furniture are common.
- Linens & towels: Mixed reviews—some find them plush, others have reported stained sheets or worn towels.
- Odors & scents: Lobby smells of woodsmoke (pleasant); some rooms have a musty/old building smell.

5 things to know before you go
💡The 'historic' charm means you might hear your neighbor's entire conversation through the wall.
💡The geothermal water is amazing, but it can have a faint sulfur smell (it's natural!).
💡You can buy a 'day pass' to the spa even if you aren't staying there, which might be a smarter play than booking a room.
💡The 'Fairmont' category rooms are shockingly small for the price point—barely enough room for a suitcase.
💡The property sits on the site of a Native American sacred spring, a history the hotel acknowledges but guests often overlook.
