I've stayed here 3 times now, it's a great place. Amazing location but also it comes with noise from being on Temple Bar. Wifi in most of the rooms.
Clean hostel but lacking in the old world feel that most hostels have in the Netherlands. It was about 1 km walk from the city center, however it was VERY close to the train station (Den Haag Holland Spoor). Wifi worked in my room on the third floor, which was a treat! Great included breakfast as well.
AMAZING hostel! I loved it so much I extended my stay. It's brand new, with sparkling bathrooms and the comfiest linen. The staff are phenomenal, will help you with anything and call you by name. Easily the best place I've ever stayed! Love it.
