I enjoyed a lot staying at Ivar's and Siri's place! Ivar and Siri are just super nice, intelligent and considerate people. And I even had this feeling of visiting some friend's house: there are lots of things in the room that clearly conveys the character of its previous(?) owner.
There is a small hall just in front of the room with a rack where you can hang your outdoor clothes, so it looks as if you have for yourself a small studio in a big house. Bathroom is very big, even huge, I would think it probably is OK for camping :) And there is a fireplace with birch-tree firewood in the room! Personally, I just loved it enormously, could watch fire for hours if I only had time.
Location is also very nice, 2-3 minutes to the metro station, and National theatre station is just 2 stops away. Very convenient. To get to the university canteen took me 6 minutes, and on the first day I even got a free food!
So, just loved my stay. Will definitely come back some day.
