After finishing my Santiago trip, here is how I would subjectively rate the properties - as always, there are full reviews and photos in the respective master threads:
- Ritz-Carlton - very friendly staff, cozy design, fluffy bed, delicious breakfast
- W - very friendly staff, nice bed, a tad worn
- Renaissance - nice suite, nice staff, nice breakfast
- Marriott - nice staff, a bit older, lots of heart despite cleanliness issue that was resolved well
- Sheraton - very traditional, comfortable
- AC - nice suite, nice macarons, great shower breakfast upsell more expensive than the RC is a deal breaker
