The apartment is clean, but spartan. It does not have a lot of cookware, or cleaning supplies. The bath supplies are touch and go, I had two shampoos but no soap or conditioner, so you may want to pack your own.
Other than that, I thought it was a lovely place to stay. Spacious and bright, great neighborhood close to food and bars, and right next to two trams and a bus line. Loved Oslo! Would definitely come again.
