Moving to Mexico City

Hi Friends,
We plan to move to Mexico City from Bangalore, India due to a professional posting. This could be for 2-3 years.

  1. How is life in general in Mexico City
  2. How much money is needed per month in USD to lead a decently comfortable life for a family of 4 with two teenage children
  3. Which would be a good, neighbourhood to rent a house for my family of 4 people
  4. Which are good international schools
    Thanks, Ashish
