You're able to drive a car in the Netherlands when you're 18, you're able to drink, smoke whatever you want, because that's when you become an adult. So, it's celebrated!
Amsterdam is well known for its canals, bikes, coffee shops and, of course, the Red-Light district.
But how do young people here spend their free time, get around and live?
Meet Cosmo, a 19-year-old student born and raised in the Dutch capital.
Today, he'll be showing us what his life in Amsterdam is like.
Goedemorgen, en welkom in mijn appartement in Amsterdam.
Or, good morning and welcome to my apartment in Amsterdam. Come with me and watch out, because the stairs are very, very steep.
So welcome to our house in the city center of Amsterdam.
My mother actually lives up these stairs. And then I live here.
So this is my flatmate. His name is Baby. He's kind of the party animal around here.
