Siren and Wilfried's place was perfect for my small family's short trip to Oslo. Communication and check-in was easy and we received lots of great child-friendly recommendations. The apartment was big and spacious with lots of toys to keep my 2-year-old busy. The location is really fantastic, right on the edge of the park with nice corner views and a really lovely walk to downtown Oslo. My only regret is not buying more coffee and pasties while we were there!
