My personal recommendations (a tiny guidebook, if you will) for enjoying 4 perfect days in Buenos Aires: also available as an app for iPhone. You also can use it on your iPod Touch or iPad.
It’s amazing what you an get for a .99 cents, especially in Buenos Aires. And, hey, if you don’t want the app then go spend those a buck on a cup of coffee over at my favorite place: Bar Británico.
The app Buenos Aires in 4 Days is available on the iTunes app store.
