Penelope was an amazing host and responded very fast during our stay. We got in later than we expected but accommodated us.
The studio is great for people with basic necessities. It's equal distance to 2 main metro stops (about 15-20min walk) which gives you options if you want to get around like a local. It's close to Chapultepec Park, which has a good amount things to do and see.
You're only a few metro stops to some other major sites and there are ecoBici bikes you can take to explore the city literally outside the door.
