Oh c'mon......there are a bunch of world class hotels in Mex City...world travelers know that......and it is hard to decide which one is better.
For a cool and chic vacation i like Hotel Habita:

The crowd is around their late 20s and early 30s and super cool partys are usual on its pool and bar. The hotel concept is all about fashion and design.
Another nice Hotel, is Hotel W Mexico City:

Businessmen and young executives are some of the clients that usually stay here.
Four Seasons Mexico City.

Majestic and Luxury at its best.
Of course, there are crappy hotels too......(and believe me crappy hotels here can scare you haha).....we are still an emerging country (or third world country) , but if you dont find any decent hotel here, is becuase you didnt made a good search...or...my friend....maybe these kind of hotels are totally out of budget.......
