The main airport used for international flights to travel to and from Buenos Aires is Ezeiza International Airport, about 35km south of Buenos Aires. Most domestic flights use Aeroparque Jorge Newbery airport, a short distance from downtown Buenos Aires. Flight information for both Ezeiza International Airport and Aeroparque Jorge Newbery, is available in English and Spanish here. From the airport, there are taxis, private cars (remises), buses, and minibuses.
Prepaid taxis (remises) from Ezeiza International Airport to downtown cost around 270 pesos plus additional costs (mainly tolls). As you exit customs there are booths on either side of the receiving area of the airport. Some of the prepaid remises will provide you with a 20% discount coupon for your airport return. If you manage to hold on to this coupon, dial them directly to come and collect you and save yourself 20%. You must also present the original receipt to receive the discount.
There are other established companies such as Manuel Tienda León (270 pesos), Go Airport Taxi Buenos Aires (275 pesos) and Taxi Ezeiza (198 pesos)
which allow for a pre-reservation online in order to guarantee your car/driver prior to your arrival which may be essential in the morning hours when the bulk of the long-haul flights arrive to the airport.
Hailing a curbside taxi is not recommended, but if one does, one should select a taxi that is dropping someone off. It will cost approximately 30% less than a remis. The cab driver will tell you a fixed price beforehand, if not, you should negotiate the price before leaving the pickup area.
The cheapest way to get downtown is to take the number 86 bus. The stop is just outside terminal B arrivals, and you need to walk 100 m. The bus will take almost 2 h to get to the Plaza de Mayo, going straight on Rivadavia Avenue and then on Hipólito Yrigoyen street. It will cost 2 pesos to get downtown. Be ready to have coins to use them on the bus: you can get change at the counters where the airport tax is paid or at any airport shop. Bus from the airport is not advised for someone unfamiliar with the city.
The Argentinian currency is the Peso (Argentinian Peso; ARP). 1 US dollar is around 4.60 pesos; 1 Euro is around 5.70 pesos; 1 Real is around 2.20 pesos. Money can be exchanged at Banco de la Nación Argentina at the airport and at any bank, ATM (cajeros) or change houses (casas de cambio). There are many banks and ATMs near the conference venue (select Mapa temático->Bancos in this map). Casas de cambio are also spread all over the city, but they are mainly concentrated in a zone known as La City. This zone is the banking district of Buenos Aires, and numerous exchange places are located right near one another. This mean fierce competition and options to check the best rates.
