Our stay was alright, the room was clean and the location was great, right next to a park and interesting sights as well as public transportation within walking distance. Unfortunately, our apartment (in the first floor) did not have a balcony and looked towards a demolished building, and the staircase was quite noisy - probably a little bit unlucky. The kitchen lacked some equipment, a coffee machine would have been nice. But it was good for three nights to experience Oslo.
