"I love this converted 1920s laboratory in North Amsterdam for its stylish, clean, and super social vibe — it has a fantastic library, dedicated workspaces and an atrium, plus a café and on-site bar. The beds are new with soft pillows, and each bunk has an individual light and USB socket; they offer an all-you-can-eat breakfast for €9.90, organize lots of activities and live events, and even let musicians perform in the ZincBAR for a free one-night stay. It's a great pick for travelers who want to get off the beaten track, and HostelPass members get 10% off." - Matthew Kepnes
