Hi,

Just to add my experience. I decided from the airport to the HGI to book a ride with taxidatum. It was 20 PEN and the driver was waiting for me. Very good professional service.
For the experience back from HGI to the airport, I just ordered Uber, and it stated it will be around 13-16 PEN, and was charged 15PEN. Another friend who arrived early and had to leave early in the morning, paid around 13 PEN for the trip to/from the airport.

Cheers!
