Doesn't get any better than Juan Carlos. This is an amazing flat in an ideal location in Mexico City. Juan Carlos was super responsive, the beds were crazy comfortable, breakfast every morning was a great way to start the day, and the flat is a relaxing place to return to after walking the city. It's also very close to the two best taco spots in the city: Califa and Tizoncito. If you have a chance to stay here you should take it.
