Andrea is a great host. She had clear instructions and suggestions when we first got to her apartment and she always replied promptly to any questions that we had. The apartment itself is very clean and cozy and corresponds to the description. It's very close to a beautiful park and there are a bunch of restaurants within 5 minute walking distance.
To get to the other parts of town you would need to use the metro, make sure you ask Andrea how to cross the highway! There are underpasses etc, so you don't have to run across it like we did in the beginning :)
We greatly enjoyed our stay in Mexico city and would definitely recommend Andrea's place as your home away from home.
