It's small but one doesn't need much more when staying a few days. The food in the refrigerator and the bowl of fruit add charm to the place, and is good to have after arriving. There are many things one can use to make the stay better like extra pillows, extra sheets, towels, umbrellas, a binder with all the information you can possibly need about the apartment and Oslo itself, playing cards, and even tea lights! I think my favorite of the whole apartment was the big windows and the possibility to sit on the windowsill and chill. Very smart and cute.
The location was great! It's as central as you can get and it's near everything. Will definitely stay there again the next time I'm in Oslo and / or recommend to people who are going to stay there.
