Christian's place is beautiful! It's very central to all the good bars and restaurants in trendy Roma Norte. He was always available to us when we had questions and was very accommodating when we had to leave our bags for a few hours after check out. The neighbourhood is very safe! Bonus: the bed and towels are extremely comfy! He even has a selection of 3-D movies to watch, which we never did because we only had a few days in Mexico City!
