This was a wonderful apartment. Small but airy. Located in the southern tip of Centro Historico just steps from the Zocalo and to metro stations that would get you to all the other neighbourhoods in the city. The apartment was clean and with all the amenities for a very comfortable stay. There were pharmacies, grocery stores, and restaurants all close by. Mario was very quick to respond to all my questions, which assured me that he would help me out should there have been any problems (and there were none). There is 24 hour doormen who are friendly and helpful. I would definitely stay here again.
