Paul and Tila are in the top 1% of the type of people you want to stay with for a prolonged period if you: 1) are interested in learning about Mexico City from a Mexican perspective 2) can reciprocate humanity and kindness 3) like karaoke and jokes that include physical humor. La Obrera is charming. I did not stay out past 1015pm (2215), but I walked all over Doctores and Obera & nothing weird or dangerous ever happened to me (took precautions - don't walk close to people/stay away from weird situations/be polite to everyone). There is excellent food in every direction & almost everyone takes cards. A supermarket is 1.5 blocks away (bodega arr), & a mall with a cinema, Starbucks, several restaurants and sam's cl is 20 mins walking. I recommend the limon pie at VIPs and the champiñones omelet at jikema cafe. close to the subway (cheap & fast). Mexico City is welcoming if you can try to speak Spanish. Luca could sell a ketchup popsicle to a woman in white gloves, como su abuelo.
