Loved Marthe's place! It's super close to a ton of stuff in Oslo - we pretty much walked everywhere the entire time. Her place is exactly like the pictures. 5 of us stayed at her place and fit comfortably. It's compact but laid out well so you're never on top of anyone. Marthe was also incredibly fast to respond to any questions we had (including restaurant recs and which cab company to use). Her building is very quiet, too, which is nice. If you've never been to Oslo, highly recommend Marthe's place! Can't wait to come back.
