We liked our stay at Olaf's apartment very much - although not smack in the centre of Oslo, it was only about a 2km walk to it and we certainly didn't take much public transport. It was very modern and well-equipped as well. The only thing that could have been improved, perhaps, was the cleanliness of some items (especially in the kitchen) - however, nothing that a quick run of the dishwasher wouldn't fix. Thank you for the great trip!
