Buenos Aires is the Best!! I've been there three years in a row and hope to go back this year. I hightly recommend staying at the Claridge Hotel on Tucuman just a half block from Florida Street. The rooms are great, the check in flawless, and the conscierge staff (Alicia and Pablo) are awesome - extremely helpful. The city has wonderful restaurants (Brocolino on Esmeralda great for Italian food; Palacio de las papas fritas is a classic BA restaurant. It's almost impossible to get less than a great meal in BA. I LOVE the empanadas. Quillmes beer is very good. The wines (malbec and chardonneys) can't be beat. The malbecs are classic to Argentina. BA is a walking city. Take a taxi to Plaza Serano and check out the botiques, restaurants, and shops. Of all the places I've traveled Argentina shares the top of the list with only a few others. I also recommend vistiing El Calafate, Ushuaia, Bariloche, and Iguasu in Argentina.. alll nice places. Have a great trip!
