Very nice stay at TK's apartment in Oslo. Fashionably decorated, airy and the balcony is quite nice. Walkable to stores, cafes and parks.
TK was quite welcoming, and helpful with any questions that I had. A friendly guy:) Use of his city bike card was very handy for me.
Be aware that his apartment is on the fourth floor if stairs are an issue. They weren't for me. TK kindly offered to help with my luggage!
Would certainly recommend.
