Great location, and the hosts are very responsive. The kitchen is spacious, and it's nice that there is a TV room. The place has a good sense of space, and it's in a nice little neighborhood, right by the palace gardens.
There's an outside door (to the street), an inside door (to the apartment complex) and then another door inside the individual room. I think consistent keyless entry for the middle room and the individual dwelling would be different from a key. Anyway, I'd suggest a change there, but there's a lot more positive than negative to share about the home and our time there.
Thank you, Wilhelm and Joanna, for making this stay option available to guests of gorgeous, vibrant Oslo.
