Ok so here's the deal I leave for Mexico on the 19th and will be staying in Mexico city for about a week and just wanted some info from people that have been there be for.

I already have a place to stay for free so I dont have to pay of that so my first question would be about how much money would I need to take down there for necessities like food and/or thing I forget to pack and to have a good time?

What are some places that are worth visiting and what areas should I avoid?

What documents do I need to take if any?

Thanks in advance.
