I´m from Tlaxcala, a city in the center of Mexico. Actually I´m living in Mexico City, Tlaxcala is very different from México City.
The climate is better in Mexico City than Tlaxcala, in the summer Tlaxcala is much hotter and in the winter the weather is very cold, however in Mexico City the climate is tempered. The transport is faster than Tlaxcala, is cheaper too.
In Tlaxcala houses are cheaper than Mexico City, and food is cheaper too. The population is bigger than Tlaxcala.
Tlaxcala is the better place to rest than Mexico City, Mexico is very loud and is very polluted.
