Cozy studio with sleeping loft in very convenient location. Really close to main train station, and a block or less from many tram and bus stops. Walkable to many popular areas, it's an excellent base for exploring Oslo. We had three travelers, one of whom slept on the pull-out sofa bed. This made things slightly cramped in that area, but it was a minor inconvenience and well worth it for our party of 3.
Great hosts - we requested a second key, and they cheerfully accommodated us. Definitely recommended.
