Hege was a great host and provides guest with everything that they could need to explore Oslo. I love that she even has books for us to peruse in addition to her detailed recommdations. I actually followed some of her suggestions and was quite pleased (do walk through the forest onto town).
What really puts her up there as a host is that she goes the extra mile to really make you feel at home. I loved the chocolate on the pillow, fresh lilies in the window, and a welcome with fruit and a pastry. Last but not least, one can just sit for hours and enjoy the view of the city from her balcony. Simply breathtaking....
In regards to distance, it is very close. You can take a bus and be at Central Station in 10 minutes.
If I return to Oslo I would definitely stay here again.
