The rooms and bathrooms were extremely clean. You sleep in your own bed instead of a bunk bed. There's a full bar and the food at the restaurant is pretty good. The staff is really helpful and polite. Plus, the hostel is about a 5-10 minute walk from the train station in Cologne. There aren't too many bars or clubs located close to the hostel.
Located near Dom, good and cheap breakfeast Parking is 10€
