This is one of the best Airbnb apartments I haver stayed in (and I have already stayed in quite a lot!) - if not the best. Extremely comfortable, very nicely set, best location in the city (if you like restaurants, bars and the lively area of Grünerløkka), and very very very clean. We felt really comfortable there, I honestly cannot think of any potential improvement.
Thore was very kind to us and extremely helpful and flexible.
In summary, highly recommended, it´s a 10/10!
