You are going to go to so many places in roma/condesa. So my advice as a mexico city born and raised: go somewhere else too…
Some things I would recommend doing:
- soccer game at either estadio azteca or CU
- centro histórico is a must and makes me crazy mad some people just don’t set foot there…
- xochimilco
- mercado de plantas de coyoacán
- some other classic/ beautiful neighborhoods to visit: narvarte, escandon, san rafael, santa maría la ribera and del valle. have fun!
