Nieves, Iván, and Lautaro are excellent hosts. Our flight arrived past midnight. Iván and Lautaro were waiting for us (outside) to check in at 2am! The apartment is fabulous and the location is perfect. The currency exchange rate in Argentina is crazy. Nieves knows a safe place nearby where you can get the "blue" rate. There's also another one next to the mall Alto Palermo. Overall, it was a wonderful trip.
