I live in the Cota Cota neighborhood of La Paz and pay USD 220 for a two bedroom, one bath apt, that includes water, electricity, and wi-fi internet. I spend another USD 100 per month on food, entertainment, public transportation, etc. I make 2-3 trips back to the USA per year (USD 850-1100 per roundtrip flight) and usually bring back about USD 300 worth of goods I can't find in Bolivia like hard contact solution, dried cranberries and blueberries, nuts, spices, chocolate chips, etc.
