Yvonne is a great host! She stayed up even though I arrived after midnight and gave me a good introduction to the place. I did not have to ask twice for wifi or keys, and she never interrupted the privacy of my room.
The place is located just in the center of Grünerløkka, and in perfect walking distance for numerous cafes and working spaces. Public transport around the whole of Oslo is accessible a minute from the front door. 10 points! I would rent from Yvonne again.
