I visited Amsterdam on my way home from a business trip and found it difficult to find a reasonably priced hotel. The Meininger was very well priced compared with other hotels. The hotel was very clean and decorated in a modern style. The room I had while very clean was very very small; ~ 6 feet by 20 feet. However, the room did have everything you would need and really how much time do you spend in the room during vacation.
The location of this hotel is very convenient just steps away from a major train station. It is just a few stops to central Amsterdam and a few stops direct to the airport. You do pay a bit for transportation but this is offset by the cost of the room.
A few watch out for this hotel.
1. This hotel very popular with school groups. The lobby was always a bit loud and busy but I did not find the guest floor to be loud.
2. There is not much activity around the hotel. There are a few places to eat in the train station (Starbucks, quick shop) but outside of that you need to take transportation into town.
Overall, a good reasonably place to stay in Amsterdam.
