K.E was very helpful. By the time I arrived at Oslo S station it was 12.15am but K.E still waited for me to show me how to get to his place. He also gave me useful information and showed me where things were on the map. I didn't see K.E much during my stay as he worked all day and I was out sightseeing. K.E's unit is about a 10 minute tram or train ride from Oslo S. You can also catch the bus. Public transport is excellent in Oslo.
