The shuttle is blue with NH hotel on the side and available on the hour and half and hour outside terminal 3. You must book with reception any shuttle to the Airport but no charge and takes 5-10 minutes. Only 20-30 minutes to Amsterdam Centraal. The room is small to medium and I was offered an upgrade for 10. We arrive early 3 times and they had rooms available every time. Their lobby is very big with free water and treats and has a souvenir store. I didn't eat at the the restaurant so cannot comment. MacDonalds literally across the street!
I will stay here every time I stay in Amsterdam!
