Lots of foreigners speculate what it would cost to live in Lima, Peru. It is true you can live very cheap in Peru, South America. But living in Lima can increase your expenses by a good percentage.
Here is a rough break down of renting an apartment for 1 month. This is just a small 2 bed apartment with a simple electric hot water shower. Simple apartments do not have hot water.
