This was a comfortable home base for us during our short, first trip to CDMX -- a well-lit space with thoughtful (designer) touches. La Condesa is traveler-friendly, as is neighbouring Roma; we enjoyed walking along the tree-lined streets, which were peaceful during the day and quite lively at night. If you're a light-sleeper, be aware that surrounding festivities can continue into the early morning. We didn't meet the host in person, but she was friendly, helpful, and very responsive via text. Any concerns we had, which were few, were addressed quickly and with care. If you're looking in this area of the city, I have no hesitations recommending Mariana's place.
