This is a wonderful & well-appointed apartment in one of the more vibrant neighborhoods in the city. The location is as good as it gets, offering everything you need within walking distance. If you get the opportunity, I highly recommend staying at Nick's place without reservation.
For those telecommuters out there (as I am), the internet is true high-speed with both wireless and hard-wired connections.
Finally, if you're in Mexico City during the "winter" months (Dec - Feb), pack a few extra sweaters. The apartment can get cool in the mornings and evenings.
