So lets say you have family coming to visit you in Oslo, but your tiny minimalist bachelor pad isn't the ideal introduction to "hygge" culture. What do you do? I highly recommend putting them up at Kari-Anne & Inge's flat, a birds nest atop St Hanshaugen, with city panoramas on one side and hundreds of books on the other, with all the creature comforts of home.
K-A & I are excellent hosts: quick with providing replies, and offer a great homemade LonelyPlanet full of tips, a travellers' guide for fellow travellers. Kitchen is well stocked too (always a plus).
As its an older building with charming views, the one downside is lack of an elevator -- the closest bus stop must be ~100M below their balcony. That height might put you off if you're used to driving your car to pick up some bread. It might have even put off the cable company, as the internet was a bit touch-and-go. But luckily you're in Norway, so you probably packed your hiking boots for those stairs, and once youre through the door, you won't want to leave until you've finished your morning tea. So pick up a book and enjoy!
