El abono de 6 dias muy útil. Funciona genial el transporte, mucha frecuencia. Pero la lanzadera con el aeropuerto un poco mal. Segun las indicaciones se puede validar el bono comprado en el mismo aeropuerto pero ahi me indicaron que tiene que ser en la estación central. Y el autobús 397 no para ahí por lo que habiendo pagado ya el abono toca andar 30 minutos o pagar un billete de 3,20 para poder llegar. Y en el caso del autobus 397 no existe un billete como tal, se supone que enseñando la reserva en el móvil es suficiente. Los conductores tanto a la ida como a la vuelta me miraron extrañados pero fueron majos y me dejaron pasar sin poner problema. Pero estaba claro que no sabían nada de ese sistema (cosa que es de entender cuando la reserva viene en español en vez de en ingles u holandés, por lo que no entienden lo que pone).

Was good to have tickets already sorted but had to get to central station to exchange tram tickets which was a little difficult as we didn’t know the city very well and the 397 doesn’t go to central (it does stop near by but we didn’t realise this as we’d never been to Amsterdam so we didn’t know place names etc).

As other review says you can exchange the online Travel ticket at front of the Centaal Station in the cream building. I tried to do this in other GVB information point without any success. The 397 bus is at the B17 or B19 sector, when you leave the airport on the main entrance it's on the right after crossing the road. All the bus drivers were very helpful and kind. On the first day of our arrival we couldn't use the ticket on other vehicle as the flight was delayed so we missed the opening hours for ticket validation, but we could get into the city with the 397 bus without any problem, then we walked the rest of the way to the accommodation. The guy in the cream building said he never seen this system before but within minutes he provided our physical tickets.
