We (my wife and our 2-years son accompany me) arrive at the evening of 16th of Aug at the Vantaa airport and need to go to the Helsinki Central Station. After googling I found out that the best way is taking the P Commuter train via Tikkurila. Am I correct?
Also, should we exit the terminal 2 of the airport to access the train at Lentoaseman Asema? What are the directions? and in what frequency does the train come at 7pm?
Finally, how much do the tickets cost, and can I buy the tickets at the station on our arrival?
Thank you very much,
