Carlos' place is absolutely perfect-- even better than the photos.
The building is new and modern with a 24 hour doorman and a parking spot if you need it (it came in handy for us as we rented a car for a day trip to the pyramids at Teotihuacan). The location in Roma Norte is perfect-- plenty of restaurants, bars and things to see within walking distance in Roma or Condesa. Reforma is a 5 minute Uber away, Centro Historico about 15 mins depending on traffic, Polanco and Chapultepec about 10 mins away.
The apartment is spacious and immaculately clean. It's so nice to have two separate rooms, each with their own bathroom. This works great for families or even for friends or coworkers in Mexico City for either a few days or even long-term. The apartment literally has everything you might need-- you could easily make this a home base if you were in Mexico City for an extended period. After a long day seeing the sights it always felt nice coming "home".
Highly recommend this place. Listen to all the positive reviews-- it's really an excellent Airbnb near everywhere you might want to be in Mexico City.
