Renate was a great and kind host, who helped us with our questions and practical issues.
The apartment was perfect for our midweek trip to Oslo (2 persons), despite some minor issues (like the electricity that fell out once). However, Renate helped us immediately when such inconveniences occured.
Conclusion: Oslo is a great city with kind people, in which you can enjoy hiking with awesome sceneries, and with beautifull architecture and musea. We would highly recommend Renate's apartment for your trip to Oslo!
