Location, perfect. Roma Norte is a quiet neighbourhood that is walkable and safe. The food choices range from the very best (don't miss Rosetta) to your local barbacoa stall. The home is tastefully decorated with lots of room to gather and for privacy. It's pretty central to everything (but everything can still be a far way away... that's typical in a city as big as CDMX). It's a great base to take off from.
