We enjoyed our stay at Lorena y Endy's place, which is managed by their friends. The space is stylish and well fitted out with everything you need without feeling crowded for a small apartment. The location is outstanding, we walked all over Condesa and Roma Norte and Sur and there were buses and trains nearby although we mostly ubered as it is very cheap in CDMX. There was reggae music on Thursday and Friday nights from the bar directly below us and it was quite loud, but we slept though it (as did our baby) so it was no issue really. We did not have any hot water the first evening, which turned into no water the next day, but the issue was dealt with by their friends and everything was smooth sailing after that. We would definitely stay here again.
