We stayed at Hillevi's place for three weeks and felt at home from day one. Hillevi and Martin treated us with fresh fruit and drinks, which was very nice. The apartment is not big, but very light and intelligently decorated. It really has everything you need for an extended city trip with children (like a washing machine and a dryer, children's cutlery, plates etc.). Martin provided us with a lot of information and tips. We were also allowed to use their bikes, with children seats at the back. It gave us the opportunity to see a lot more of Oslo than a tourist normally does.
Our sons also had the time of their life in this apartment, with a play/bedroom filled with toys. In the backyard there is a small playground with a sandpit and swings. Little bicycles and toys are lying around everywhere and can be used by everyone. In general, we really loved the place and would definitely come back here!
