I would use Europcar for future rentals.

Excelente auto, otorga seguridad en todo el viaje. Muu buen servicio

Europcar have a useful, private car park at Balmaceda airport so that you can avoid paying parking charges. The car we rented was in good shape and did the job we wanted very well. The only issue they have is that the lines for picking up or returning cars can get a bit long when a flight has just arrived or is shortly to depart so give yourself plenty of time to complete these procedures.

Useful booking platform. Definitely helped us save money over the counter price.

Very good car and service from Europcar Balmaceda, friendly staff at the pickup counter in the airport terminal, staff also spoke little english wich was very helpful due to our limited spanish skills.
