We (my girlfriend and I) stayed at Paula's place for nearly a week for our stay in DF. The unit was large enough for us to spread out, but you could have easily fit another two people there too. We didn't use the kitchen at all, as there are a ton of great restaurants (and bars) within walking distance. The location is an awesome home base for your Mexico City trip, as La Condesa is a peaceful oasis in an otherwise hectic city. We never waited more than 2 minutes to catch an Uber from here, and it was generally a 10-20 minute ride to wherever we wanted to go.
