I had a fantastic stay at David's studio. The apartment is in a pretty, quiet courtyard off of a pedestrian street in the heart of the Centro neighborhood, very close to lots of great restaurants, the tourist attractions in and around Zócalo, and two metro stops. He even equipped the apartment with drinking water for my stay, which was a much appreciated touch. He could certainly charge more for such a well kept, well located, and spacious rental; the stay was worth every penny.
