A perfect place to stay in Oslo! 2 mins away from the metro station which takes you into the centre in a couple of minutes. You can walk it in less than an hour too. Kumiko is always around and provides excellent communication, she was present for check in and gave me a map of Oslo including lots of good spots to try.
The bed is comfy and there are some storage options in the room. I'll be coming back if I'm ever in Oslo again!
