This flat was great, located right in the middle of the Centro Historico of Mexico City, just around the corner from the pedestrian mall stretching between the Zocalo and the Alameda. Despite its location, it was not noisy. The flat itself is perfect for two people; for three or four the couch in the living room can fold down into a double bed. Although we never got to meet Marcia face to face, she had everything arranged for our arrival. A friend was there waiting in the lobby of the building. Marcia responded promptly to all our emails both before our arrival and while we were there. We will definitely stay here again and recommend Marcia's place to anyone coming to Mexico City.
