If you're just coming in from the airport late at night or leaving on a flight early in the morning, this place is perfect, that is true. Also, I would add, there's a little square just north of this apartment where you can get pastries and across from there is a taqueria (Taqueria Leo, I think) where the vibe is friendly and the food is amazing. I had read reviews saying not to wander around at night if you stay here and that may be true but my girlfriend and I were out until about 11pm and never felt unsafe. The place feels like a neighborhood and at night seemed pretty sleepy.
For those using the metro, it's a very close walk to the b-line and from there it took us only 20 minutes to get to downtown Mexico City. Much faster than the bus/taxi.
Overall, perfect place for the price and airport convenience.
