The apartment was just as described, clean and comfortable. Host was very accessible and responded quickly to any questions that popped up. The apartment is a 3rd-floor walk up (2nd floor for Europeans) situated on a main street in Condesa, with a modern coffee shop just below, convenience store across the street and other cafes and shops a few steps away. Laundry and small hangout areas were on the roof. There was some construction in the building behind which made it noisy in the bedrooms during the day (living room/dining area were on the other side and quiet) - if silence is a must for you, I’d just check to see if any work is still going on. I would definitely come back and also recommend this apartment to friends visiting CDMX.
For the pre-travel Covid test required to return to the U.S., I walked into a Chopo pharmacy nearby…there was about a 30 minute wait and results sent by email within an hour or so, which was much less stressful than waiting to do it at the airport.
