Concierge.com's insider take:
Forget the various shades of gray that distinguish many of this chain's locations. To remind you that you're in Latin America, the W Mexico City is splashed with bordello red. It's the color of the pillows in the lobby, the tables in the Whiskey Lounge, and the chairs in the Cocoa Bar. In the restaurant, Solea, red panels give you a bit of privacy. (But since this is a hipster hangout, the panels are semitransparent, so that you can still see and be seen.) And don't forget the 237 bedrooms, where red walls add a sensuous touch to rooms that otherwise would be a bit sterile. All have up-to-date amenities such as Wi-Fi (for a fee), DVD, and CD players, and a few bizarre—but pleasant—touches such as hammocks in the bathrooms. Big windows mean good views over the greenery of the posh Polanco neighborhood.
