I just finished up my two night stay here using points and a Free Night Certificate. I really went back and forth between the Waldorf Astoria, the Hilton, and the Doubletree in Amsterdam. I decided to go with the Waldorf because the reviews are excellent and the location is convenient to where I wanted to go. Overall, I am happy with my decision and enjoyed the hotel. I am going to post some general observations about the hotel that can perhaps help others in the future. First, I booked a day room at the Hilton Schipol Airport because this hotel could not guarantee an early check-in (and as mentioned in another post, seemed to discourage it). So, instead of arriving at 9am, I showed up at 3pm. I took an Uber from the airport (which I probably would not take again). The app showed the cost as 38 Euros but my ultimate charge was 56 Euros. I probably should have taken the train and tram to the hotel instead. Second, the service was flawless and friendly. I ate two breakfasts and one dinner at the hotel and enjoyed the bar for a bit. Everyone went out of their way to make my stay special. I was also given a free drink at dinner and not charged for two phone calls to the United States. The staff will sincerely try to get to know you and make sure you have a good time here. Unfortunately, I am not really sure how much of an upgrade I received as a Diamond member. I booked a King Superior Plus Room and was given a King Premier. This is supposed to be two room categories up. However, the Premier room looked about the same as the Superior Plus room in the pictures to be honest. I had a view of the garden. Speaking of the garden, I wish they allowed people to eat breakfast out there in the morning but they do not. Finally, the hotel is about a 20m minute walk to the Rijksmuseum and 25 minutes to the Anne Frank House. There are many restaurants and bars around.
