It's very central, only a few hundred meters to the main street Karl Johans gate. You nearly have everything you need in that apartment. A small kitchen, with pans and pots and whatnot, a bed and a table that you can collapse to have more room space.
The bathroom also has a washing machine which is easy to use.
Only thing missing was basic cooking stuff (oil, salt and pepper), it's kind of wasteful to buy this stuff only for yourself well-knowing that you will never completely use it during your stay. Hopefully the oil and salt I bought will stay for the next person who stays in the apartment.
