We really enjoyed our stay in Alex's apartment. Alex was very easy to communicate with and responded quickly to questions that came up during our visit.
The apartment is clean and the extra bedrooms and bathrooms came in handy when we had friends who are from more remote parts of the city come for a visit.
There are cafes and food/snack stands, a 7-11, a big mall, a beautiful walking boulevard (Reforma) and a metro stop, all within a block or two.
