Our stay at Kukun was very nice, even though it was just one night. The area is very central, near Angel de la Reforma. The unit is high enough that there's minimal noise filtering in, which is great. There is front desk security as soon as you get in, so it feels extremely safe overall. The apartment does get very warm during the day because the windows are so large and the AC unit is small, so you'll just have to blast it for a while before it cools down. The only downside is that the bathroom water temperature and pressure were on the lower side, not really a problem most of the time since it's warm in Mexico City but just take quick showers. Overall, a great stay! The apartment is beautiful. Finally, they let us leave our bags at the apartment until 2p which was a lifesaver for us.
