I, my wife, 6 year old and 3 year old stayed for 4 nights. For us, it was just what we were looking for. It was clean, comfortable and a short bus ride into the centre of Oslo. The kitchen was simple (fridge + stove with 2 rings), which was fine for cooking simple meals (there is a supermarket nearby). The sofa bed was comfortable. My thanks to Trude for telling us the nearby Sofienbergparken was a good place for the kids to have a run around in.
