Sandvika Hotels with Free Parking.

This hotel is very much NOT located in Oslo, it is on the outskirts. There is a train station nearby, so you can get the train from Airport to the railway station and then a taxi to the hotel (It is not walkable). The hotel staff are friendly and efficient, the restaurant offered good food and the breakfasts were excellent. The room was clean, had a desk and good Wi-Fi. Nearby is a large shopping mall that offered some additional dining options and a supermarket. Overall this is a solid option if you are in business in this district, it is not an option if you want to be in central Oslo.
