The building where this apartment is located is very secure. I felt save and had lots of privacy. Make sure to get the contact info for the concierge and arrange with them to get access to the building in advance, if let's say, your flight arrives to CDMX late.
The place is amazing. It has a great layout and is spacious. I'm a fan of the room with the sun roof, which has a suitable table to set up a laptop to do work. But not enough sunlight seems to come through to the apartment, even on sunny January 70°+ F (21+° C) days, which leaves the place drafty and cold. Some guests, like myself, would probably be happier if there had been a provided space heater. :)
