Carlos is an amazing host, we booked his place last minute from Los Angeles to Mexico City and it couldn't of been even better. The location is at a really fair walking distance from the touristic areas and he was really understanding with our needs. It totally felt like having a little home in the City and it was easy to get around the area as well. I can honestly say his place has everything you need during the trip.
Even if you need any advice or help with anything you can definitely text him and he'll answer your questions immediately, he can even come to you in order to see you have everything you need.
Most definitely going to book his venue every time I fly into the City.
