Mexico city, wonderful place with a lot of places to visit, but do you have not much money? Here I have some options:
Chapultepec
Zocalo
Coyoacan
Ciudad Universitaria
- The subway is a good idea for to move arround the city, but be careful and choose hours with less people.
- Don't keep your money in the same bag.
- Avoid crowdy places or too alone.
- Walk with local guides
- Enjoy!
