Very good location. Close to everything. Quite area. Very clean and warm room, even outside was real Norwegian cold.
Jang is like a shadow, you can see her, only if you looking for her :-)
It is not stress to live with them in the same flat at all. As I said, they are very polite.
Christian is really helpful host.
For sure, if I'm going back in Oslo, ill choose this place again.
Ask them for fish market on the harbor. You can have fresh fish almost for free.
