I love Luz's book nest. The house is uniquely decorated with all the things you need for a comfortable stay. The location is great to me, quiet and safe with easy access to public transportation. It's also near Coyoacan (great night market with lots of local food). It's a pity that we didn't get the chance to meet Luz in person due to our tight schedule, but she had been very accommodating since our booking was confirmed. She always responded promptly to our requests/questions. I recommend this place to everyone who will stay in Mexico City.
