Doesn't really have a hostel vibe. Rooms are really small, and there's no aircon or a fan, and it was really hot at night. The breakfast room looks like a huge canteen.
You have to pay to rent a towel, which is quite absurd, considering how expensive the hostel is (yes, I know it's Switzerland, but still).
Huge pro, though: you get a big locker which is activated by your key.
Bathrooms are not bad either.
Stay here if you only need a bed, but don't expect much else.
