The short version is that if you book this place be prepared for annoyances. We were ultimately okay during our 20-day visit but would never rebook.
The long version is that Kukun appears to be running a pseudo hotel, with 13 units in a partially built out high-security building at the southwestern edge of Condesa. Construction workers and noise abound, and one of the two elevators was often in dedicated service for the crews meaning long waits for the remaining car. Our check-in process was horrendous, with the security staff acting like they were secret service agents protecting the president. Kukun did not tell them we extended by a day at the end, which led to interrogations at checkout. We got the distinct feeling that the building administration is hostile towards Kukun for using their building as a hotel and in fact, I wish that Airbnb would penalize these kinds of hosts in some fashion for violating the spirit of the service.
There were too many negatives to list here but the worst was that in our case at check-in they forced us to unload our dozen or so bags and boxes at the curb instead of the garage, and then complained and took pictures of us when we were forced to wait at the top of the main entrance. The Kukun rep that was supposed to meet us and facilitate entry was over an hour late and not helpful.
The apartment itself was cozy and well appointed, but on the small side for the price with not even a full size sofa in the tiny living room (just a love seat). Want to relax? Go to bed. You’re definitely paying for location here and the gorgeous north facing view of the city’s skyline. The problem with most buildings in Mexico City that are of this particular size and modernity is that they are built alongside highways, and this one is no exception. Be prepared for 24/7 road noise and exhaust, with the worst being the double-trailer semis hitting their engine brakes as they approach the busy intersection at circuito interior and the eje.
