Marthe’s flat is in a nice area close to the center of Oslo. Public transport is right around the corner. Still the place is very quiet and you look out onto foliage (right now in beautiful autumn colors).
Although an open space separated only by two doors (to the bathroom and personal area), thick curtains guarantee privacy and since Marthe is a very kind person, she offers the use of her kitchen and living area.
I can recommend a stay at any time.
