Julia makes you truly feel at home, or better. She's always available and ready to help, and when she's busy she'll send someone right away. The listing is accurate. The location couldn't be better (it is indeed "at the heart" of Condesa, one of the two or three best neighborhoods to be as a tourist, with all kinds of restaurants, cafés and if you so choose nightlife.) She's genuinely interested in learning about you and giving tips about the city and beyond. I couldn't have had a better experience.
