Rio de Janerio, a very very nice place to spend vacation. I visited Rio some time ago and still I get caught when listening to a brazilian accent. Its people, simple the best hosts I can remember when traveling to South America. I was on a business trip for more than a month and I was treated so warm I came back a couple of times more.
..Barra de Tijuca, Brasil (a 30 minutes drive from Rio), Beautiful beaches!
