Francisco is an excellent host. He and his son, Diego, are very welcoming, friendly, and responsive. My boyfriend and I stayed with them for a week and by the third day our room already felt like home. We had all the privacy we needed and felt totally comfortable asking Francisco for recommendations and advice. Our departing flight left in the evening, and Francisco let us leave our luggage in the apartment until we left for the airport. The apartment is located in a charming, residential neighborhood and about a 15 minute walk to the metro. I would highly recommend Francisco's place for anyone visiting Mexico City.
