Oscar's place is fantastic. Exactly as described. Of all the airbnb hosts we have had, Oscar was by far the best. He checked in regularly to see how things were going and to offer advice (even offered to change our towels in a 5 day stay!)
The neighbourhood is lovely with great restaurants located a short walk away. Do go to El Califa for some quick and easy tacos.
It's super easy getting around the craziness of Mexico city from here.
I can't recommend this appartment highly enough.
