Updated in 2018 : Courtyard by Marriott Mexico City Revolucion Review (formerly Radisson Mexico City Flamingos)
The Courtyard by Marriott Mexico City Revolucion is located a bit outside the trendy Mexico City neighborhoods of Roma and Condesa - it sits on their southwestern flank along the busy Avenida Revolucion. While the immediate neighborhood isn't dangerous it is certainly a step down from safety level of Roma, Polanco and Condesa in terms of safety. The Courtyard by Marriott Mexico City Revolucion is the former Radisson Mexico City Flamingos and during the re-flagging just a few details inside the rooms have changed. In the lobby just the branding changed. Check-in was easy with the newly trained Marriott agents (my check-in during Radisson times was a mess).
I compared my pictures from three years ago to the current room and couldn't find any visible differences besides plenty of power plus near the bed and desk area.
