One word: WOW. This place looks every bit as stunning as the photos. The owners did a heck of a job designing and furnishing it, truly.
The kitchen is gorgeous and well-stocked, and the furniture throughout the house is great.
It does face a very busy street, so it gets quite loud when you open the windows, but quiets down a bit when you close them. If you are a very light sleeper you will need ear plugs.
Its location is super close to everything you'd want to go to - the parks in Condesa nearby are a beautiful stroll in the day or evening, and the Taco Naco is a great /cheap/no-frills taco shop on the same street when you need a quick bite. Walmart Express is a 6 minute walk for more grocery selection, and there are a ton of restaurants/bars very close by (we particularly loved Baltra Bar).
Overall I'd recommend you stay and enjoy this gorgeous home!
