Laura has a great space in a very safe and convenient location. It's a one bed walk-up with a couch that folds down, and it has a very welcoming and artistic vibe to it. Laura was always easy to contact, and the instructions she left were easy to follow. She is a great host who really looks after her clients.
The location is a 12 minute walk to the Sevilla metro stop, and for those who wouldn't think twice about taking public transportation, please reconsider: the metro gives you a ground-up view of the city and its people; it is subsidized such that it costs about $0.27 US per ticket; and most importantly it gets you where you need in probably far less time than crawling through traffic with a car. And yes, Mexico City traffic is bad! It is on par with La Paz, Bolivia and Jakarta, Indonesia.
It is also a half hour walk to the world class Museum of Anthropology and the rest of Chapultepec Park. And again, time wise, you're probably better off walking than taking a car.
Great food nearby, too, from the atole and tamale vendor in the morning to the best tacos al pastor we found in the city just a couple of blocks up north in front of the OXXO market after 8PM.
We had a great time at Laura's place, and we recommend it highly.
