We stayed in Harald's place for a month. It's a beautiful and very spacious two-level apartment, fully equipped for a longer stay. The surrounding area is a quiet neighborhood - mostly families with children. The apartment also has a beautiful garden and is close to the subway and supermarkets (7/8 minutes walk). Harald is a great host - very responsive and caring. We had the pleasure of meeting Harald in person and had a great time. Highly recommend for longer and shorter visits to Oslo.
