 Please pay attention that every time you purchase a paper train ticket one extra euro would be charged as admin fee 
 The hotel is 8 min walk away from the Sloterdijk train station from which u will be in the city center in only 6 minutes by train The most economic way to the center actually is to buy GVB day ticket at the Spar supermarket next to the train station with that it allows u unlimited GVB bus tram ride during the day bus 22 from Sloterdijk sends u to center in 20 minutes Yes train and bus are run by different companies thus GVB day ticket doesn t allow u to take train
