Our stay was just about perfect. The location is amazing, very safe, very accessible to other parts of CDMX, and has tons of things around the neighborhood (bars, restaurants, supermarkets, pharmacy, etc.). My mom was very nervous to visit CDMX but felt at ease as soon as we arrived. Horacio is very responsive and helpful, and even provided safety documents for the building's structure and earthquake prepareness (there was an earthquake a week before that was felt in CDMX too). The apartment is very beautiful, spacious, clean, quiet and bright. The apartment seems to have noise proof windows because when you shut all the windows you can't really hear the street noise at all, and so sleeping was easy for me (I generally need almost total silence to sleep). Getting in and out was very easy (Horacio provides video instructions for just about everything), and the security men at the door are very helpful and polite. If you didn't plan what to do ahead of time, Horacio provides info and guides that are available in the apartment, including a Spanish phrase book. I honestly thought I could live here forever it was so nice and everything went so smoothly.
