Espen and Cathrine were great hosts! The apartment was clean, and very centrally located. It has all the amenities you would need (I stayed there for 3 months and rarely encountered any problems), and even if something came up, Espen was always happy to help out.
I’d highly recommend staying here if ever on a trip to Oslo. You’re located right on one of the most popular bus lines, and the tram is a couple minutes walk. I have nothing bad to say!
