Some people might be daunted by the location. But in fact, the location worked out very well for what I needed it for. In megalopolises such as NYC, Chicago, or Mexico City, there's really no such thing as "central"-it really depends on what you want to do and where you want to center yourself. You strategize. And that's what I did, knowing that I will be at a conference in UNAM during this stay. The host had sent detailed instructions on how to get to this place from the Coyoacan metro station (Viveros). Later, I also found out how to catch a bus to the Metrobus (this stretch is also very walkable) which opened up other possibilities such as a trip to the lovely completely-untouristed borough of Tlalpan. The wifi here is plenty strong even from my bed, but there are at least three nice hipsterish cafes with wifi nearby for working. The one I really enjoyed is on Revolucion (and is called Reevolucion) and is open from 6:30 to 9. Just north of this airbnb is a stretch of traditional taquerias (maybe 6 of them in a row) famous for their al pastor. You're given a key when you arrive and come and go as you wish. The security is tip-top however, as I noted several security camera,s including one facing the staircase as one walks up. I did not visit San Angel during this stay but note the relative proximity (a short ride or longish walk) of the famous Bazar Sabado. Finally, I must thank the hosts for their warm welcome and for the detailed instructions on public transport that they gave me!
