I had 24 hours in Amsterdam with an early morning flight out. The shuttle service to and from the airport runs on schedule. There is an uphill walk from the shuttle stop to the entrance of the hotel. It is an easy walk, but could be problematic if you have a lot of luggage. I caught the train into the city center from the airport. For my purposes, this was great, however, I would choose a hotel in the city center for a longer stay in Amsterdam.
The rooms are small and basic, but new and very clean. The front desk staff could use a lesson in customer service. The front desk attendant was preoccupied with handling random tasks and never bothered to acknowledge the waiting guests. If not for the reliable airport shuttle and newness/cleanliness of the facility, I would have lowered my rating.
This is a great option if you need easy access to the airport. The ride is about 15 minutes.
