This place is a great price in a great location. We LOVED Mexico City.
The elevator was out while we were there--but we knew that ahead of time. We could not get the WiFi to work--but our friends rented an apartment above ours and we just hooked up to theirs. One reason we picked the place was because we had a group of 6 adults and it was nice to be able to get separate units in the same building.
Our apartment was clean and quiet--in part because the windows are not really "exterior" windows. The spot above us that our friends rented had a great view but was pretty noisy (it is a noisy part of town).
Having AC in the bedroom was nice. It was cool enough at night without it, but we are used to having AC.
It would be nice to have more than one key because you need it to get in and out of the building.
