I used this service on a recent trip to Argentina, and was very satisfied. I booked 4 trips, either to or from airports in Buenos Aires and Puerto Iguazu. All prepaid upfront, no hidden costs, very reasonable prices. Very convenient, bypass the long taxi line at the airport. Each time the driver contacted me by WhattsApp ahead of time to confirm, and then again a few minutes before pickup, with details of meeting place and photo of his car and license plates. All 4 drivers were on time, polite, courteous, drove clean maintained cars, and got me to my destination quickly and safely. I recommend this service and plan to use it again.
