Nice room in a good location within walking distance of the major station, a 30sec walk from an underground metro station, and close to all the major attractions (approx 10min walk to the opera house).
The room was comfortable with a large bed.
The bathroom was functional, and had a nice warm shower.
I never met Gung and Martin, as they were away, so their mother-in-law was staying in the apartment. I didn't have much to do with her, as she kept to herself.
Overall, a nice room for your time in Oslo, conveniently located and comfortable
