The apartment is amazing !!! It's so huge and new and clean.. the location is very good too, 5 minutes walking from the city center and very close to the train station.
The view is incredible (There's even a telescope in the apartment!)
The staff in the reception were very helpful and kind. Elwin was extremely nice.

If you go to Den Haag, you MUST book this apartment.

The restaurant is recommended as well, good and quit special food, not expensive and very good service.

Great experience!
