My sister and me stayed at Hilde’s and John’s for two nights. They’re great hosts and were extremely helpful in giving us insider tipps how to get around the city and what to see. Their beautiful apartment is perfectly adapted to welcoming guests, and we never felt like intruding or being. The complimentary coffee is an extra incentive for getting out of the very comfortable bed to discover the nice city of Oslo. The flat is conveniently located in walking distance between the center/sea side and the up and coming Gruenerlokka district with its parks. We did everything by foot, the walk to train station is 15 min.
