The location is easy to find and in a center of Oslo, near to central station, bus terminal, shopping center, various restaurants and many site touristiques reached on foot. The apartment is right next to Gronland station too.. Gung and Martin are nice and communicative host, fast in responding email or knock2 the door at anytime as long as they are at home. Do not worry of being unwarm when you arrive; warm and clean room, water, tea, dishes are ready. Kids are cute and I guarantee you have your own privacy too. Will stay again at their place for sure.
