I just had a great stay at Jorunn's place.
Her flat is nice and sunny, with very design-y furniture and lots of plants - a modern art museum! The room itself is not huge but cosy, and Jorunn welcomed me to use the rest of the flat.
Bathroom and kitchen were spotless and the livingroom had a comfy sofa and an incredible view over Oslo.
Location is great, a five minute walk from Toyen station , the Bothanical Gardens and the Munch museum.
Definitely recommended for a stay in Oslo!
