We are a family of 5 (3 children aged 12, 10 and 8) bicycling through Europe. We had a pleasant stay at Magdalena and Kenneth cottage. It's a cute little house and a nice place if you are planning to visit. Oslo is reacheable in just 25 minutes with the tramway (same with a bike) and the Technic and science Museum is at walking distance (definitely worth a visit). There were also plenty of board games, which we appreciated a lot.
The place is definitely too small though for a family planing to stay inside on rainy days.
