Depends on how you want to live. You can use Western facilities, restaurants, food items, etc. and pay similar costs to London. But you can also live on a couple of dollars a day buying locally produced food at markets, sticking to non-imported products and things not designed for immigrants.

And travel is very cheap, often < $1 for a 1 hour mutatu ride.
