Marta's apartment is in an amazing location; 2 minute walk from Bellas Artes and 10 minutes from Zolaco, with restaurants nearby as well.
Marta is very communicative and offered lots of recommendations. The apartment was clean and stocked with anything needed.
There is a roof deck on the building that is great to hang out on, and has an amazing view over CDMX.
There is a 24 hour doorman, so we felt safe the entire trip.
