I stayed at Jorplace Beach Hostel last week (December 2011) - to be fair it probably isn't the best time to stay near the beach, but it's one of the few hostels in The Hague.
The hostel was alright. It includes breakfast which is actually pretty good for a hostel (meats along with bread, cereal, tea, coffee, etc).
The problem I had with the hostel was the triple bunks. I originally booked a bed in a four person dorm, but was told on arrival they no longer do these so she gave me a slightly cheaper rate and threw me into a 6 person dorm. The room was tiny and with 6 beds in there I have a lot of trouble believing 6 people could even fit in that room along with luggage. Luckily for me it was winter so I only shared the room with one other person - I would not advise staying here in summer when it's full, would be insane and really hot.
Everything else was great. The people there were really friendly, and the reception people were incredibly helpful - I hired a bike on my second day which was relatively cheap.
All up, it's an alright hostel - it has the basic amenities, but the rooms could do with massive improvements.
