The accomodation is really nice and cozy. Although the location is close to the city center (my girlfriend and me could walk downtown in 20 minutes), it feels like being in a quiet town!
The apartment has a rather big living room plus a small kitchen, where one can cook, but only with a microwave oven. A big bedroom on the second floor. Bus stop just 100 meters, a shop open until 23, restaurants and bars right across the street.
Debbie let us the exclusive use of the apartment, and she was always available for questions and helping with the touristic informations we needed. She also let something for breakfast in the fridge. Very positive experience that let us appreciate Oslo more.
