Johan Blyttsvei 30, Bergen
The bus number 31 leaves Strandgaten in the middle of the city centre, outside the Xhibition shopping centre (in Smastrandgaten), and from Kong Oscars gate near the railway station. It uses approximately 15 minutes, and when you exit the bus, you'll be about 200 metres from the youth hostel. Look for a nearby sign.
To find us from the railway station, leave through the main entrance (under the big neon clock, through the terminal). Head to your right, and continue walking until you get to the main road (named Kong Oscars gate). Turn right, find a bus stop at the same side of the road, and take bus no. 31 (the name of the bus is 'Laegdene').
