Kristian was a great host. He picked me up from the central station, explained to me a lot about Oslo and how to navigate through the city.
The apartment was amazing. It has a beautiful view over the Oslofjord on the balcony and I had my own bathroom. The room itself was small but was cozy.
The metro, supermarket, and restaurants are just 5 minutes away, and the way was easy to find.
Highly recommend staying at his apartment.
