I highly recommend Dani and Gerry's place for those visiting Mexico City.
Unit: Spacious, clean, flexible. There were six of us and we had plenty of room to gather as well as to spread out when desired. The space is clean and modern. The only thing to be aware of is that the evenings get cold in Mexico City and there's no heat in the building, so you may want to bring some warmer pajamas
Location: Can't be beat. Close to restaurants, coffee shops, bars, nightlife, but extremely quiet. We walked everywhere and felt lucky to have such a central base for our exploration.
Hosts: Responsive and friendly. Dani and Gerry were great leading up to the trip and also very responsive when there was an issue with internet access at the house.
