We had a great stay at Kukun - we especially liked the catchphrase, Embrace the Meanwhile. The airbnb was really nice, spacious, and clean. It took a little bit of time for the hot water to get running the first day, but after that, we had no issues with hot water. The building has security 24/7, which we really appreciated, and we felt safe there. It was super walkable to everything in Roma Norte (and even Condesa).
