Jan is a great host, always responds quickly, provided instructions on how to get to his place with images, and even recommended places to check out. He was very friendly, always responsive on the chat and it was nice talking to him in person as well. The apartment was really clean and very well connected, you can take the trams, metro or buses, everything is close by. There is even a 24 hour supermarket right next to the apartment, which was perfect for us as we arrived late and checked out early, so we could still get something from the supermarket there. Would definitely stay with him again when we come to Oslo again, and would recommend him to anyone staying in Oslo, especially if you enjoy getting to know local people.
