This place is what it is. Be open minded. For me it was a good place to stay during my visit in Oslo. I felt safe and found peace at night, especially as the place is quiet and in a fully enclosed backyard. I slept like a baby :) To stay here you must keep in mind that this is some form of shed made as a mini house. This is not an apparatment, and at least not a hotel room. Its a small cabin, fully equipped with what you need for your basics. It has heated floors, a small window, a small kitchen, two beds (1 x bunk and 1 x camping mattress). loved it, even though the last guest acctually stole the picture from the wall and the smoke alarm. Jesus christ.. The location is great, situated in Grünerløkka walking distance from everything you might need.
Enjoy the calmness of a primitive and quiet stay. I will for sure come again to this place. And referring to a bad review I just read in here about this place: not true at all.
I would not have my honeymoon here, but I would personally prefer this place before booking a cheap hotel room. This is a cabin made for real people and not divas. It is what it is, not more and not less.
I will book my next stay here. :) Looking foreward to my next time here.
