The apartment is spotless, we loved it, it will definitely be our first choice if we return to Oslo. The beds are comfortable, it has everything you need to cook and wash, plus the loft is very bright and cool.
It is very well located, close to the metro like two blocks away, supermarket is a block away and there is coffee shops within the same 1-2 blocks. There is a bus that passes near about 2 blocks from the apartment for the airport flybussen and starts operating at 3:57 am.
One recommendation is to buy the transportation (works for metro, ferry, tram, bus with the # symbol) ticket at the airport or city at a 7-eleven, there a 24 hr pass, since we could not find a place near the apartment that sells it.
