Salvadors apartment is really lovely. Staying in the appartment was a special experience in itself. The glass doors are pretty much walls that open so lots of fresh air which I loved. If your not familiar with the neighborhood, Couyocan is great. It doesn't feel like you are in such a big city when you are there. Great feeling place, I traveled alone here and felt very safe. Lots of restaurants cafes and shops nearby. Walking distance to tons of stuff.
