Cannot recommend Rocio's home enough. We were 4 girls staying here, and two guests more could comfortably fit, sharing the Queen beds. The couch folds out to sleep another person, which isn't ideal, however if your party is okay with this sleeping arrangement then I would say this Airbnb comfortably sleeps 7.
Also to keep in mind, this apartment is on the 4th floor of a walkup. This wasn't an issue for us at all, but good to know before booking.
Rocio was a speedy communicator and keeps a stylish and clean home. I'll be recommending her home to other friends who are planning a trip to Mexico City. I already cannot wait to return!
