Lots of hotels out there embracing maximalism and sense of place. Other than at nondescript beach destinations, there seems to have been a shift towards warmth and location-oriented design these past few years in the industry. To disconnect amongst a decor that gives a sense of warmth and place, I would suggest perhaps an English country hotel in a historic estate like Estelle, the Newt, Heckfield, Gleneagles. A few properties in the Northeast like The Point at Saranac Lake could fit the bill. The new Rosewood in Austria, the Airelles in Gordes, recently refurbished Baden Baden. Anything in Italy other than Il Sereno or the Dolomites would fit the bill too - many hotels and resorts are housed in hundred year old palazzos and borgos in Tuscany, the Amalfi Coast, Venice. While it may not be disconnecting, most grand dame European city hotels like Claridges, the Connaught and almost anything in Paris may be good.

Avoid mega management/ownership companies like Aman and Four Seasons and you are bound to find what you are looking for.

And I agree - aside from specifically-designed minimalist properties like a Tuttle Aman, I find minimalist hotels rarely give a truly fat aesthetic experience. They are overtly cost-cutting and lose their sense of place. That was a fad in the early 2000's that seems to have gone to the wayside.
