"The Top of the City Oslo Plaza is an eco-friendly hotel located next to Oslo Central Station and a short walk from the Oslo Spektrum Arena, handy if you're going to concerts! It's also just a stone's throw from the beautiful opera house. This giant of a hotel has a total of 37 floors, and houses several restaurants and bars, including the 34 SkyBar with excellent views of the city below. There is a spa and a high tech fitness centre, as well as a valet car service."
