Taxi from the bus station to the hostel will cost approximately $3000. You can also use a colectivo (shared taxi with a sign on the top) that will cost $600. The colectivo station is immediately right on the south side of the Bus Station. From the airport just ask for Aji Verde Hostel or Vicuña street N 415 central zone. Or just call us on the number which is on your confirmation email of your booking. It will take about 25 minutes to get here from the bus station on foot.
