Driving in Buenos Aires is more trouble than it’s worth for a tourist. The city streets are clogged and chaotic, and parking is scarce. Renting a car for your stay will prove to be a hassle, especially considering that the public transportation system (buses and the subte) and taxis can get you anywhere you want to go. Most hotels can also arrange private transport, if you prefer. If you do have a car, some hotels provide parking, but it is usually off site, and they will probably charge a fee.
