The sport place was only for trainers, nothing else you can do except drive bike, walk/run and skis. The first day I discover there was some hair on my towel, the next day two extra towels where laying down in a room...?? because cannot use sport room, I did train in the room, and when was pumping I could see the underneath of a bed, and it was really dirty over there. The bedsheet looks like old with wholes in some places.. The menu for diner is very small, almost nothing to choose.
I like wireless, was good enough for 5th floor as I need use VPN and work. Two elevators make going up/down easy. The supervisors are nice and helpfull, free parking is big bonus for The Hague hotels. Having condition is nice too.
