This apartment is in an amazing area, and the set up and décor are absolutely beautiful. We loved our trip to Mexico City and this was a perfect location for two people who wanted to explore the city and access great restaurants, bars, and shops by foot.
But there are a few things I wish I had known, given the price of the rental. First, as other have noted there is no sound insulation. Although the apartment is three floors above a very quiet park (which is beautiful!) You will hear everything that happens outside (e.g., cars, dogs, café patrons). There's also some sort of industrial fan on the building's roof that runs periodically. If you're a light sleeper, I would not stay here. Second, like many places in Mexico City, the water is not drinkable. Additionally, our bathroom had a bad sewer smell that came from the toilet. We alerted the host, who had the bathroom cleaned, but it didn't fix the smell.
