I spent 1 night here last week. I would not really recommend it when touring Den Haag.

First, it's in a pretty isolated location. You have to take the tram about 20 mins just to get downtown. Very annoying. I was "upgraded" to the club floor but otherwise the room was standard. The hotel seemed to be having maintenance issues - leaky roof, several electrical operations going on, etc. Hotel website advertises a hotel shuttle service, but when I called to be picked up from the train station I was told the shuttle only goes to the Shell business office (???) and some other random place. 25 euro taxi ride later I'm at the hotel. So the shuttle is useless (unless of course you work for Shell). Club lounge was average with average offerings.

One thing to note - you can buy tram day passes from the front desk. That was helpful.

While I got an entire bottle of wine as a Plat welcome gift at the AMS Marriott and the Rotterdam Marriott, this one sent me ONE GLASS of wine. How wonderful.

The room itself was fine, typical "new" Marriott design.

Stay somewhere else.
