I truly enjoyed my experience staying at Karla's. The location was as best as you could ask for while traveling to a place as large and vibrant as Mexico City. Her apartment is located in the Historical District of downtown. It's extremely close to a subway station and numerous food/merchandise cart vendors. The apartment is very rustic,authentic, and also has all the modern amenities one would need to be comfortable. Karla keeps an extremely clean home as well. On the ground floor of the apartment building there are about 3 cafe/bars that open early for breakfast and stay open really late serving beer and drinks. Karla was truly a fantastic host. She was extremely kind and we spent a good amount of time talking about our past travel histories. Her place comes highly recommended from me and I think that anyone traveling to Mexico City should utilize Karla for a wonderful experience.
