John Richard and Hilde are wonderful hosts with a wonderful property that they've gone to great lengths to make welcoming and well-appointed for their guests. The flat is on a private street, with a park within steps of their front door. Guests have robust WiFi access, and the hosts are a wealth of local knowledge (I particularly encourage you get recommendations for local restaurants and night life). I will definitely be dropping a line next time I'm planning to be in Oslo. Highly recommended.
