Where I am may seem obvious, but be careful.
I am part of a small area estranged from its original country, inside a country that is itself extremely small.
My country borders only one other, and is on the sea.
Visit my country if you want a taste of the first world in a part of the world surrounded by less wealthy nations.
Visit my country if you want to experience one of the most multi-cultural cities in the world, eat great food, see one of the cleanest cities the world over, and experience a nation that may just be more advanced and modern than your own.
Where am I?
