The place and the location are amazing. La Roma is definitely one of the best place to stay in Mexico City.
The contact with Virginia was poor though. We never saw her, she barely respond to our messages and never pay the wifi.
In the other hand, the people we had contact with, the guardians of the building and the housekeeper, were very kind and helpful.
Also, if you traveling in the winter, consider that generally the buildings in the city are not well isolated and it can be cold at night.
