I booked the room and the host gave me the wrong room . So the wrong one is actually for the other guests. He came back at about 11pm with other guests and found me in the wrong room and start to yelling at me and say some bad words . I didn’t do anything wrong , and got humiliated. I decided to move out and find the hotel to stay in middle of the night . There was some drunkards outside and I also scared to toke the metro alone , so I walked 20 mins to get to the hotel . That’s it. I was so happy and that’s my first night in Oslo . Thank you !
