We enjoyed our stay. Martha welcomed us and was very helpful and pointed us to the right places and even mailed a letter for us that we left behind. Since it was our first experience with airbnb we somehow thought it was a private apartment. But they live there too. Even so, we were comfortable and had a private room and bathroom. The location is great and Martha and Manuel were very welcoming and kind. We felt very safe with them, and it actually worked out great, since it is the first time in 30 years we had been in downtown Mexico City. I recommend staying with Martha and Manuel.
