Don't know about the apartments, but you catch the no. 3 bus from the Airport to the final stop in the new bus terminal in Puerto del Rosario. Cost's €1.10 per person. Make sure this bus is going to Puerto del Rosario as the No. 3 also services Caleta de Fuste going the other way and both stop at the same bus stop outside departures at the airport. At the new terminal, jump on the no. 6 to Corralejo, costs €2.90 pe person. Bus services are extremely reliable and punctual and more often than not, the arrival of the No. 3 is just a couple of minutes before the departure of the No. 6.
