It was a great Air BnB experience for me with John Richard and Hilde! When I arrived at their apartment (having followed their very clear directions) they were waiting to welcome me & proceeded to give me a detailed overview of Oslo & its attractions - including some details for places off the tourist track.
Everything about the apartment was as described including the great location & very comfortable bed and I had a very happy 3 days there.
As a light sleeper I did use my earplugs as there was noise from the park outside my window but they worked well as usual
If you have the opportunity to visit Oslo then I'd certainly recommend staying here
