You can get from the airport to Casa Los Ajaches by rental car, taxi or bus. To come by bus, you have to combine two different lines. First you have to take line 161 from the airport to the bus station in Playa Blanca and then take the bus line 30 to the stop of Las Coloradas. At 600 meters from the stop is the urbanization Jardines de Papagayo and Casa Los Ajaches. Lanzarote Intercitybus google searches on the official website and find all the information regarding schedules of bus lines. (The page does not allow me to put links) If you plan to rent a car and do not have available the GPS, write me and send you the instructions.
