I stayed here in the beginning of May. In fact this skyscraper with apartments is an analog of 4*-5* aparthotel. Each apartment has its own kitchen with necessary kitchenware (otherwise, there was a small lack of kitchenware for me), reception desk is placed on the ground floor, also hotel restaurant is located in this building.
If you want to visit the Hague you should stay in this skyscraper. All apartments are enough for comfortable live in the city, excellent location in the city near railroad station, and additionally nice overlook of the entire city because the apartment is placed on the 30th floor. The domestic wifi was without problems.
I definitely recommend this apartment for residence in the Hague.
