Stayed in the hostel in summer 2014 with friends (from Australia) who came to KRK to visit me.
We stayed in 6 bed dorm. Great staff, helpful and friendly. Clean bathrooms. Not right in the center but at least it was quiet and without all the party noises from the street like in the market square. We paid only 30 zł per night and the room was really big(first floor). Hostel booked for us trips to Wieliczka and Auschwitz and we also definitely recommend them.
