Excellent location right by the tram line and busses, easily walkable to Oslo S and nearby neighborhoods. Somewhat noisy with the ambulances leaving all hours of the day, but I appreciated the location as it's easy to walk to lots of shops, restaurants, and bars.
Breakfast is good, typical Scandinavian hotel breakfast options of fresh fruits and veggies, warm buffet, etc.
Rooms: Room size was OK and clean. However, to me, my room was quite dark (even in June), the lighting was two bedside lights, a lamp by the table and then a few track lights above the TV. Windows helped, but one window was rather small (maybe to help sleep in summertime?).
Beds were comfortable and bathroom was quite small (expected). Only issue was the shower doors were odd and did not keep water from spreading across the bathroom floor so I would need to use a towel every morning as a floor mat, and my bathroom door somehow was broken/bent (metal got bent at bottom of door?) by housekeeping during my stay so that it wouldn't close. Not a big issue but odd occurrence.
That said, hotel rooms are primarily for sleeping which I was able to do. For me the location and breakfast made up for the shortcomings of the room.
