Siw's place is cozy, very clean and has everything you may need. Also, Siw did a great job in making the place a good example of Nordic interior design.
It is a great launch pad to visit the city. You can reach nice bars and restaurants in 5-10 minutes, the Kongressenter in 10, the main shopping street in 20 and the City hall area in 25ish.
Communicating with Siw was very easy, and I also had the pleasure to meet her at check in. She is naturally helpful and interested in people and their cultures.
I highly recommend staying at her place!
