Really well located appartment. There is a coffee shop and a supermarket down the streets, it's around 20 min by walk from Oslo S.
Easy access, really great for a short stay. You need to walk stairs to reach the appartment.
The inside was clean and had basic kitchen ustensils. The bed was confortable. The bathroom has a washing machine, which is convenient.
I totally recommand this AirBnB for a short stay, it is definitely the cheapest option I have found.
