The best way to go from Ezeiza Intl. Airport to Buenos Aires downtown and also to return to the airport is Manuel Tienda Leon.
You can rent a remis (kind of executive service) for ARS 105,00 or you can take a bus. The time schedule for buses is in the website.
Do not take taxis outside the airport. We didn't have any trouble with taxis, but the locals says that they can give you fake money as change.
You'll find the Tienda Leon counter outside the arrival gate, turn to your left.
This is the bus service to and from the airport. Its in the neighborhood of 30 pesos per person one way. They run the main bus into town to their terminal and then use minibus shuttles to get the passengers to their final destinations. So it is an airport to door service, just with a pitstop at the main terminal in town.
Due to the pricing I would say if you are traveling with anyone else, this is more expensive than just getting a taxi.
The cheapest and safest way to get to and from the airport was using the Manuel Tienda Leon bus service. When you have gone through customs at the airport you will come to a round hall with a lot of taxi, bus and accommodation booths. Look for the one with the big Lion on it and book a bus to Plaza San Martin for $25 Argentinian pesos. For $2 pesos more you can get a transfer ticket that will take you to your hotel from the Plaza.
Manuel Tienda Leon is a private bus company that goes from its office in Bs As to Ezeiza. The ticket office is right outside the airport, just after you exit the international terminal. When I used this service, tickets cost about $15-$17 (U$S 5-6). They will leave you at their office on Av Santa Fe, near Plaza San Martin.
To get to Buenos Aires from the international airport, Ezeiza, you can take a cab. As soon as you step out of the terminal there will be about 20 drivers trying to persuade you to hire them. If money is no object, this is not a bad way to go. They will help you with your luggage and drop you off at your destination. When I left, it cost about $35 (about U$S 12) including tolls. Make sure when the drivers quote you a price, they're including the tolls (peaje) in that price. PLEASE NOTE THAT PRICES MAY HAVE CHANGED SINCE THEN. THIS INFORMATION IS BASED ON MY LAST TRIP IN 2003.
If it's your first time in Argentina, you might be a little dazed like I was after flying all night in an uncomfortable plane! Also I was by myself. So if you just want a sure, safe thing when you arrive at the airport, walk right over to the Manuel Tienda Leon car stand. It was $58 pesos into town ($19 U.S.) which is about a 30-minute ride. It's a flat rate no reservations required.The driver was very courteous and friendly, air conditioned car and he made sure I got into my hotel before pulling away.
As soon as you have picked up your luggage and emerge into the ground transportation area, you will see a large booth for the Manuel Tienda Leon shuttle-bus service into Buenos Aires, located 35-km (20-miles) north of the airport.
My Visa credit card did the trick for our A$23 (US$7.50) each one-way cost for a drive into the city on an air-conditioned Mercedes-Benz bus. The highway into Buenos Aires is a very modern divided highway with nice scenery (and the associated government financial corruption is one of the reasons for Argentina's financial crisis that has resulted in this being such an amazing place to visit from abroad!). Once the bus has weaved it's way into the city, it stops at a small terminal near the Rio de la Plata waterfront, where you transfer to vans for delivery to your final destination.
The service was fast and efficient. When leaving BA, we took a private taxi from our hotel to avoid the hassles of bus connections, and it cost us a total of A$50 (US$17), not much more than the bus trip and a lot faster. The photo shows our inbound bus at the downtown transfer station.
Once you get out of the customs and immigration there are booths for you to buy transportation to the city.
if alone, get manuel tienda leon buses which go every twenty minutes to downtown the cose is 22 pesos
once there for an additional peso or two there would ferry you to the down town area hotels or hostels.
if more than one person, i advise you to take a taxi or a remis.
From Ezeiza (International Airport ) to Downtown my suggestion is take Manuel Tienda Leon bus, is cheap and confortable bus. Its possible to book and leave/take your hotel.
Ezeiza to downtown is just 22 pesos
The cheapest way to come from the EZE airport to the centre of Buenos Aires is to take the MANUEL TIENDA LEON buses.
To depart from the centre of Buenos Aires for the EZE airport, go to the MANUEL TIENDA LEON office at Avenida Santa Fe 790, near the Plaza San Martin.
Leaves every half-hour in either direction.
If you buy directly from the office, it should be slightly cheaper (12 Arg Pesos), compared to buying the ticket from, say, your hostel.
The bus of Manuel Tienda Leon from and to Ezeiza International Airport in Buenos Aires is a cheap alternative (19 argentinian pesos) 24 hours a day. It leaves you (and takes you) in the center of the city (Santa Fe 790)
From the airport or getting to the Airport... And I refer to EZE (international airport...) you want to take a Remis (private hire car) as well, but you can do better than just hailing one down. Le Coq seems to do a GREAT job of getting you to the airport in lots of time and is very resonable rate. I paid 22 pesos one way. I paid road tolls in addition. Give them a buzz.
