The host, Mari Carmen, was really helpful and accommodating throughout my whole stay, making sure that my stay was comfortable and pleasant and going out of her way to make sure everything was OK. The location is really superb. It is only a few blocks from the very fast and cheap metro, which I used daily. Within walking distance is a park which I used for running; a few cafés which serve delicious huevos rancheros, baguettes, and paninis for very cheap prices; a market (it was called City Market), which had groceries. The neighborhood was a really nice and safe one too!
