You cannot go wrong with Line. I booked to stay with her at the beginning and end of my trip and it was perfect! While the location isn't right in the sentrum, it's a 20 minute walk and it truly gives you a taste of Oslo as a native rather than a tourist. It's located right near Viglendsparken.
The room is wonderful and spacious as described! She went out of her way on my second stay to leave me fruit, which was very appreciated and delicious!
Connie, is the sweetest pup around and Line is one of the best hosts I've gotten to stay with!!
