I stayed in Guadalupe's apartment for a month. She was very communicative and helpful – pointing out the nearby mercado, and even giving me a metro card with a few rides on it. The neighborhood is muy tranquilo. Great antojitos on the corner – tacos, tortas... and a juice stand. For evenings out I would sometimes walk to a bar in colonia Roma (usually around 30 minutes). I came home quite late some nights and never felt unsafe. Overall great value and Guadalupe is a delight.
