Plus Berlin is more hotel than hostel, which speaks to its excellent service, relative cleanliness, quality of amenities, and breadth of activities and services offered with local businesses.
Small things like the extremely courteous service (24 hours, by the way), free towels, sleak building design, spacious rooms and hallways, TONS of pub crawl tours each day of multiple varieties, ample selection of daily activities, and more separate Plus from the pack. Sure, some of these things sound like things every hostel offers, but I think what's different about Plus is the sheer number of activities going on both inside and outside the hostel. It's also very affordable (roughly $20 USD/night for a 6 person room), located close to the trains/clubs, has a pool/sauna, and very fast wifi.
