We had a wonderful time in Mathilde's flat. It's cosy, quiet and clean - It has a great location - ten minutes walk to the main station, and not much longer to the city centre. She also has some great tips for what to do around the city - we had an amazing meal in one of the restaurants she has on her page. We had an emergency which meant we had to change our flights to arrive late in Oslo, and she was super flexible and helpful in finding a way to give us the key. Highly recommend staying here!
