Our stay was gorgeous. The modern apartment is in a fantastic location with Grünerløkka being trendy but very quiet at night. The building is extremely secure. Our host responded to our queries rapidly and was friendly and helpful. The bed is a sofa bed but fine for a weekend stay and the place has all the amenities needed, as well as being super close to tram stops, restaurants, shops, and a lovely 20 min walk from Oslo Center. We would recommend to a couple or single traveller (definitely at Christmas time) - the people in Grünerløkka are very friendly!
