At the first day what i stay, i arrived too late cause my plane delayed. She worried about me, and she took me at the 'statoil' even late night. She borrowed two guide books for me. That helped me so much.
The best thing in her place was that is warm, cozy place and nice view. If you like walking, you have to walk arround there. And there are two market near the house and metro is so close from house. That's why you would be comfortable during staying.
If i visit oslo again, i hope to be able to stay in her house.
