I have stayed in Airbnbs all around Mexico City for the last year, and this is by far the best location and nicest Airbnb I have come across. It is in arguably the safest neighborhood, and sits right on a park. The walk around balcony is incredible, and the floor to ceiling windows let in tons of light and make you feel as if you are in the park. It really is just an absolutely amazing location. The building is quiet because there aren't a lot of residents, and the doormen are incredibly nice.
I must have been on the of the first guests to stay in this Airbnb, because everything was brand new. Because of that there were some issues in figuring out the hot water - which wasn't working at first, but we were able to resolve that during my stay. Everything else relative to the apartment was flawless. The only room for improvement I could think of was Capitalia's firmness on checkout time. They were very strict about leaving at 11am and even changed the door code right at 11am.
