The host is very hospitable. The apartment is super clean, neat, and accommodating. Breakfast is very delicious. Great location. Walking distance to most of the main tourist attractions. There is a tram and bike rental station nearby.
One thing to keep in mind as a guest, that you should follow the instructions as the host requires to meet the guest to let them in and to give the key. Be proactive on informing the host on your estimated arrival time. Loved Oslo!
