Ivonne and José Luis' apartment was an excellent place to stay in Mexico City. My friend and I spent a long weekend there, and it was a perfect base to explore the city: central, clean, comfortable, and boasting a lovely view! Ivonne and José Luis themselves were also great hosts. They gave us plenty of tips for exploring, had guide books available in the apartment, and were very responsive to all our questions. (They live in the apartment next door, so getting and returning the key was very easy.) Highly recommended!
