This hotel is very conveniently located just across the street from the railway station. There are normal hotel rooms as well as cheaper hostel rooms. These have bunk beds, but you are not sharing rooms with strangers. If you are staying in a hostel room you have to use the bathrooms in the corridor. The furniture is old and worn, but it is clean and cheap. I haven't stayed in the hotel part, so I don't know what it's like. There are kitchens that you can use, but you can also pay 60 sek to have breakfast, which was well worth its price. The receptionist was very nice and makes you feel welcome.
This is a good option if you are on a tight budget, but want to avoid staying far away from the centre.
