Esteban,
You will not like Lima. You asked for honest. I have a house outside of Dallas, Texas. In the US I golf, fish in the Gulf of Mexico, enjoy leaving windows open at home and the keys left in the car.
What I love about Peru and Lima is that for me, often the US is TOO quiet, TOO civilized, TOO relaxed and TOO boring. What I like about Lima is it is in many ways kind of like the Old West was in the US 150 years ago. In Lima, today, it can be dirty, chaotic, at times questionably dangerous, and police don't always catch every little violation. I LIKE THIS.
For me, and many like me, Lima can be a place to drop off the radar. Go under the radar. Have an adventure of sorts. Part of the fun of living in Lima is never knowing what will happen next. For me Lima is now normal like any other place. Driving in Lima is normal, like any other place. The governmental chaos and often times corruption is normal, but I know how to play the game.
If you are simply looking to relocate into a culturally rich, exciting, relaxing, interesting place where you can settle in and go to sleep each night in paradise -- Lima isn't it my friend.
If you're looking for adventure, smog, dust, traffic, noise and anxiety - and love adapting to these things which are surrounded by an amazing country (Peru), then you'll love it as so many do.
I love living in Peru, because it is the OPPOSITE of the US. I get a sense of reward knowing I can make it in a place that most others cannot. That is the bottom line.
