AMAZING LOCATION. The location and state of the apartment are great: clean and modern. There are a few things I feel like I should list for people new to CDMX: even though it's on the 4th floor, the street noise at night can be loud; it will be warm during the day, there is no A/C, so be sure to close the blinds so the sun doesn't bake the apartment; it's on the 4th floor (5th floor if you're American), there is an elevator but just an FYI if you take the stairs.
The location can't be beat and it's a great apartment for the cost. I recommend staying here if you don't want to be in a hotel and want to experience local life.
