~15 euros for a bed in dormitory, we paid 68 euros iirc for 4 bed private room.
its a youth hostel, not hotel. located in rather nice area, just accross the river from old town, about 20mins walk. if there's no fog great view from the balcony at night. the only problem with it is that the serbian person looking after things there at night tells you to shut up and go to room at around 11 at night
