I was at the Crown Plaza city center for two nights; as the name says, its location is right in the city center between central station and dam square on Nwz. Voorburgwal behind the damrak.
The check in was fast and corteus; as we were a party of four, we got two rooms, one on the first floor and another one on the second floor.
We booked a superior room not on the club floor; the rooms were beautifully and modernly decorated and they were a good size, very comfortable bed, working desk, coffee and tea making facilities, large lcd TV (with hdmi connection and audio in to plug your ipod, lan) tea table and chairs. Wifi connection is quite expensive, but there is the business center with two computers connected to the internet and it's free to use. The bathroom had a tub with shower and was not that big. The heated floor was a nice touch.
The room on the first floor was overlooking the back courtyard of the hotel, so not much of a view, the second floor room instead was at the corner of the building and had a view over Nwz. Voorburgwal. Although it was overlooking the street, no noise was heard.
The lobby lounge has a modern fireplace and it's a nice place to relax or read a book.
We also used the complimentary sauna at the fitness center that is open 24h and it was great when the outside temperature was near to zero.
Breakfast was quite expensive at 30 Euros; there is a café right on the opposite side of the hotel where you can get a full american breakfast with coffee and fresh orange juice for half the price.
We asked the concierge for a restaurant suggestion, but he just handed us the card of a very touristic Dutch restaurant close to the hotel; but as it was not our first time in A'dam, we asked for something not touristic, so he didn't help that much.
For a contemporary decor, location in the middle of the action, but away from the hustle and bustle, safe area (security is also granted by the elevators that need the room key to work) the Crown Plaza is an excellent choice.
