The unit is spacious and modern, with a spectacular view of the city. It is definitely a bargain for what you get. The kitchen has all modern appliances and very adequate cooking supplies if one is going to be there for more than a few days. The building is a 5 minute walk from the Hague HS rail station (not the Central Station), and 2 tram stops from the Central station. My arrival was in the AM on a weekend, and the main desk where you sign in and get a key is not open until noon, so plan accordingly. Weekdays they are there from early morning on.
As the building is near the rail station, there are countless fast food, ethnic and take-away eating places, as well as a full size Albert Heijn market - kind of like Trader Joe's on a smaller scale: groceries divided into 1-2 person portions. Note also that the location is not quite central old section Den Haag: that is a 15-20 minute walk or few stop tram ride away. Would not hesitate to rent again.
