Karla's place was very cute and in a very safe location! My friends living in Mexico City even commented on how nice her apartment was. The place was very comfortable for two friends to stay in, and while the listing mentions a "sofa bed," it was actually a second bed that was very comfortable. Karla was a great host and responsive to questions. Some small notes are that the bathroom doors don't fully close, which can be a little awkward. Also, sound definitely carries in the building, so I understand why there is a strict policy about not having parties late at night. Overall, I would definitely recommend Karla's apartment to any of my friends who are visiting Mexico City!
