Karim was very helpful and made me feel at home. He even met me at the train station and helped me get to the apartment with my luggage when I got in pretty late. The room is small so it's great for an single person or a couple. The apartment is located a couple blocks from the waterfall on the Akerselva with a nice path along the river that you can walk to get to lots of shops and restaurants in the area. Thanks Karim!
