We had an amazing time staying in Oslo at Martine's apartment. She was really welcoming, interesting, friendly, fun and with loads of great suggestions about where to go around town. The flat is bright and airy, with lovely high ceilings and very comfortable. The Christmas tree was still up when we visited and together with the fire it felt very homely. Great location in Grunerlokka, right across from one of the best cafes in Oslo, and only a couple of minutes from the nearest Tram stop. Can't recommend highly enough!
