Oslo not being a cheap location it was great to find Huilings place. You stay with her mother who stays in her room while you use the living room with kitchen with complete privacy. We can barely tell she was there. There is a supermarket nearby 2 minutes as well as a tram station.
It was a little bit hard to find the apartment since there are 3-4 buildings in the same complex but she is very responsive so if you have any question you can message her
