Our stay at Henning's place has been really lovely. The house is very cozy and has everything you could wish for.
We especially enjoyed the well-equipped kitchen, a big selection of board games and the proximity to a big public transport station from where you can go basically anywhere in Oslo within 20 minutes.
All-in-all a great place to stay, if you want to stay out of the inner city hustle, but still be within reach of all the great spots in and around Oslo.
